September 2020 Nagorno-Karabakh clashes

The Second Nagorno-Karabakh War was an armed conflict in 2020 that took place in the disputed region of Nagorno-Karabakh and the surrounding territories. It was a major escalation of an unresolved conflict over the region, involving Azerbaijan, Armenia and the self-declared Armenian breakaway state of Artsakh. The war lasted for more than a month and resulted in Azerbaijani victory, with Armenia ceding the territories it had occupied in 1994 surrounding Nagorno-Karabakh. The defeat ignited anti-government protests in Armenia. Post-war skirmishes continued in the region, including substantial clashes in 2022.

Fighting began on the morning of 27 September, with an Azerbaijani offensive along the line of contact established in the aftermath of the First Nagorno-Karabakh War (1988–1994). Clashes were particularly intense in the less mountainous districts of southern Nagorno-Karabakh. Turkey provided military support to Azerbaijan, although the extent of this support has been disputed.

The war was marked by the deployment of drones, sensors, long-range heavy artillery and missile strikes, as well as by state propaganda and the use of official social media accounts in online information warfare. In particular, Azerbaijan's widespread use of drones was seen as crucial in determining the conflict's outcome. Numerous countries and the United Nations strongly condemned the fighting and called on both sides to de-escalate tensions and resume meaningful negotiations. Three ceasefires brokered by Russia, France, and the United States failed to stop the conflict.

Following the capture of Shusha, the second-largest city in Nagorno-Karabakh, a ceasefire agreement was signed, ending all hostilities in the area from 10 November 2020. Under the agreement, the warring sides kept control of the areas they held within Nagorno-Karabakh at the time of the ceasefire, Armenia returned the surrounding territories it had occupied since 1994 to Azerbaijan, and Azerbaijan was guaranteed transport communication to its exclave Nakhchivan, bordering Turkey and Iran. Approximately 2,000 Russian soldiers have been deployed as peacekeeping forces along the Lachin corridor connecting Armenia and Nagorno-Karabakh, with a mandate of at least five years. Following the end of the war, an unconfirmed number of Armenian prisoners of war were captive in Azerbaijan, with reports of mistreatment and charges filed against them, leading to a case at the International Court of Justice.

Naming

The war has been referred to as the "Second Nagorno-Karabakh War", and has also been called the "44-Day War" in both Armenia and Azerbaijan.

In Armenia and Artsakh, it has been called the "Second Artsakh War" ( hy, Արցախյան երկրորդ պատերազմ, translit=Arts'akhyan yerkrord paterazm), "Patriotic War" and the "Fight for Survival" ( hy, Գոյամարտ, Goyamart).

In Azerbaijan, it has been called the "Second Karabakh War" () and "Patriotic War". The Azerbaijani government referred to it as an "operation for peace enforcement" and "counter-offensive operation". It later announced it had initiated military operations under the code-name "Operation Iron Fist" ( az, Dəmir Yumruq əməliyyatı).

Background

The territorial ownership of Nagorno-Karabakh is fiercely contested between Armenians and Azerbaijanis. The current conflict has its roots in events following World War I and today the region is ''de jure'' part of Azerbaijan, although large parts are ''de facto'' held by the internationally unrecognised Republic of Artsakh, which is supported by Armenia.

Soviet era

During the Soviet era, the predominantly Armenian-populated region was governed as an autonomous oblast within the Azerbaijan SSR. As the Soviet Union began to disintegrate during the late 1980s the question of Nagorno-Karabakh's status re-emerged, and on 20 February 1988 the parliament of the Nagorno-Karabakh Autonomous Oblast passed a resolution requesting transfer of the oblast from the Azerbaijan SSR to the Armenian SSR. Azerbaijan rejected the request several times, and ethnic violence began shortly thereafter with a series of pogroms between 1988 and 1990 against Armenians in Sumgait, Ganja and Baku, and against Azerbaijanis in Gugark and Stepanakert. Following the revocation of Nagorno-Karabakh's autonomous status, an independence referendum was held in the region on 10 December 1991. The referendum was boycotted by the Azerbaijani population, which then constituted around 22.8% of the region's population; 99.8% of participants voted in favour. In early 1992, following the Soviet Union's collapse, the region descended into outright war.

First Nagorno-Karabakh War

The First Nagorno-Karabakh War resulted in the displacement of approximately 725,000 Azerbaijanis and 300,000–500,000 Armenians from both Azerbaijan and Armenia. The 1994 Bishkek Protocol brought the fighting to an end and resulted in significant Armenian territorial gains: in addition to controlling most of Nagorno-Karabakh, the Republic of Artsakh also occupied the surrounding Azerbaijani-populated districts of Agdam, Jabrayil, Fuzuli, Kalbajar, Qubadli, Lachin and Zangilan. The terms of the Bishkek agreement produced a frozen conflict, and long-standing international mediation attempts to create a peace process were initiated by the OSCE Minsk Group in 1994, with the interrupted Madrid Principles being the most recent iteration prior to the 2020 war. The United Nations Security Council adopted four resolutions in 1993 calling for the withdrawal of "occupying forces" from the territories surrounding Nagorno-Karabakh,
and in 2008 the General Assembly adopted a resolution demanding the immediate withdrawal of Armenian occupying forces, although the co-chairs of the OSCE Minsk Group, Russia, France and USA, voted against it.

Frozen conflict

For three decades multiple violations of the ceasefire occurred, the most serious being the four-day 2016 Nagorno-Karabakh conflict. Surveys indicated that the inhabitants of Nagorno-Karabakh did not want to be part of Azerbaijan and in 2020 the Armenian prime minister Nikol Pashinyan announced plans to make Shusha, a city of historical and cultural significance to both Armenians and Azerbaijanis, Artsakh's new capital. In August of the same year the government of Artsakh moved the country's parliament to Shusha, escalating tensions between Armenia and Azerbaijan. Further skirmishes occurred on the border between the two countries in July 2020. Thousands of Azerbaijanis rallied for war against Armenia in response, and Turkey voiced its firm support for Azerbaijan. On 29 July 2020, Azerbaijan conducted a series of military exercises that lasted from 29 July to 10 August 2020, followed by further exercises in early September with the involvement of Turkey. Prior to the resumption of hostilities, allegations emerged that Turkey had facilitated the transfer of hundreds of Syrian National Army members from the Hamza Division to Azerbaijan. Baku denied the involvement of foreign fighters.

Course of the war

Overview

The conflict was characterised by the widespread use of combat drones, particularly by Azerbaijan, as well as heavy artillery barrages, rocket attacks and trench warfare. Throughout the campaign, Azerbaijan relied heavily on drone strikes against Armenian/Artsakh forces, inflicting heavy losses upon Armenian tanks, artillery, air defence systems and military personnel, although some Azerbaijani drones were shot down. It also featured the deployment of cluster munitions, which are banned by the majority of the international community but not by Armenia or Azerbaijan. Both Armenia and Azerbaijan used cluster munitions against civilian areas outside of the conflict zone. A series of missile attacks on Ganja, Azerbaijan inflicted mass civilian casualties, as did artillery strikes on Stepanakert, Artsakh's capital. Much of Stepanakert's population fled during the course of the fighting. The conflict was accompanied by coordinated attempts to spread misleading content and disinformation via social media and the internet.

The conflict began with an Azerbaijani ground offensive that included armoured formations, supported by artillery and drones, including loitering munitions. Armenian and Artsakh troops were forced back from their first line of defence in Artsakh's southeast and northern regions, but inflicted significant losses on Azerbaijani armoured formations with anti-tank guided missiles and artillery, destroying dozens of vehicles. Azerbaijan made heavy use of drones in strikes against Armenian air defences, taking out 13 short-range surface-to-air missile systems. Azerbaijani forces used drones to systematically isolate and destroy Armenian/Artsakh positions. Reconnaissance drones would locate a military position on the front lines and the placement of reserve forces, after which the position would be shelled along with roads and bridges that could potentially be used by the reserves to reach the position. After the Armenian/Artsakh position had been extensively shelled and cut off from reinforcement, the Azerbaijanis would move in superior forces to overwhelm it. This tactic was repeatedly used to gradually overrun Armenian and Artsakh positions. Azerbaijani troops managed to make limited gains in the south in the first three days of the conflict. For the next three days, both sides largely exchanged fire from fixed positions. In the north, Armenian/Artsakh forces counterattacked, managing to retake some ground. Their largest counterattack took place on the fourth day, but incurred heavy losses when their armour and artillery units were exposed to Azerbaijani attack drones, loitering munitions, and reconnaissance drones spotting for Azerbaijani artillery as they manoeuvred in the open.

Azerbaijan targeted infrastructure throughout Artsakh starting on the first day of the war, including the use of rocket artillery and cluster munitions against Stepanakert, the capital of Artsakh, and a missile strike against a bridge in the Lachin Corridor linking Armenia with Artsakh. On the 6th day of the war, Armenia/Artsakh targeted Ganja for the first of four times with ballistic missiles, nominally targeting the military portion of Ganja International Airport but instead hitting residential areas. On the morning of the seventh day, Azerbaijan launched a major offensive. The Azerbaijani Army's First, Second, and Third Army Corps, reinforced by reservists from the Fourth Army Corps, began an advance in the north, making some territorial gains, but the Azerbaijani advance stalled.

Most of the fighting subsequently shifted to the south, in terrain that is relatively flat and underpopulated as compared to the mountainous north. Azerbaijani forces launched offensives toward Jabrayil and Füzuli, managing to break through the multi-layered Armenian/Artsakh defensive lines and recapture a stretch of territory held by Armenian troops as a buffer zone, but the fighting subsequently stalled.

After the shelling of Martuni, Artsakh authorities began mobilising civilians. Just before 04:00 (00:00 UTC) on 10 October 2020, Russia reported that both Armenia and Azerbaijan had agreed on a humanitarian ceasefire after ten hours of talks in Moscow (the Moscow Statement) and announced that both would enter "substantive" talks. After the declared ceasefire, the President of Artsakh admitted Azerbaijan had been able to achieve some success, moving the front deep into Artsakh territory; the Armenian Prime Minister announced that Armenian forces had conducted a "partial retreat".

The ceasefire quickly broke down and the Azerbaijani advance continued. Within days Azerbaijan announced the capture of dozens of villages on the southern front. A second ceasefire attempt midnight 17 October 2020 was also ignored. Azerbaijan announced the capture of Jabrayil on 9 October 2020 and Füzuli on 17 October 2020. Azerbaijani troops also captured the Khoda Afarin Dam and Khodaafarin Bridges. Azerbaijan announced that the border area with Iran was fully secured with the capture of Agbend on 22 October 2020. Azerbaijani forces then turned northwest, advancing towards the Lachin corridor, the sole highway between Armenia and Nagorno-Karabakh, putting it within artillery range. According to Artsakh, a counterattack repelled forward elements of the Azerbaijani force and pushed them back. Armenian/Artsakh resistance had managed to halt the Azerbaijani advance to within 25 kilometres of the Lachin corridor by 26 October 2020. Artsakh troops who had retreated into the mountains and forests began launching small-unit attacks against exposed Azerbaijani infantry and armour, and Armenian forces launched a counteroffensive near the far southwestern border between Armenia and Azerbaijan. On 26 October 2020, a US-brokered ceasefire came into effect, but fighting resumed within minutes. Three days later, the Artsakh authorities stated that the Azerbaijani forces were from Shusha. On 8 November 2020, Azerbaijani forces seized Shusha, the second-largest city in Artsakh before the war, located 15 kilometres from Stepanakert, the republic's capital.

Although the amount of territory contested was relatively restricted, the conflict impacted the wider region, in part due to the type of munitions deployed. Shells and rockets landed in East Azerbaijan Province, Iran, although no damage was reported, and Iran reported that several unmanned aerial vehicles (UAVs) had been downed or had crashed within its territory. Georgia stated that two UAVs had crashed in its Kakheti Province.

Ceasefire agreement

On 9 November 2020, in the aftermath of the capture of Shusha, a ceasefire agreement was signed by the President of Azerbaijan, Ilham Aliyev, the Prime Minister of Armenia, Nikol Pashinyan, and the President of Russia, Vladimir Putin, ending all hostilities in the zone of the Nagorno-Karabakh conflict from 10 November 2020, 00:00 Moscow time. The President of Artsakh, Arayik Harutyunyan, also agreed to end the hostilities.

Under the terms of the deal, both belligerent parties were to exchange prisoners of war and the bodies of the fallen. Furthermore, Armenian forces were to withdraw from Armenian-occupied territories surrounding Nagorno-Karabakh by 1 December 2020, while a peacekeeping force, provided by the Russian Ground Forces and led by Lieutenant General Rustam Muradov, of just under 2,000 soldiers would be deployed for a minimum of five years along the line of contact and the Lachin corridor linking Armenia and the Nagorno-Karabakh region. Additionally, Armenia undertook to "guarantee safety" of transport communication between Azerbaijan's Nakhchivan exclave and mainland Azerbaijan in both directions, while Russia's border troops (under the Federal Security Service) were to "exercise control over the transport communication".

On 15 December 2020, after several weeks of cease fire, the sides finally exchanged prisoners of war. 44 Armenian and 12 Azeri prisoners were exchanged. It is unclear whether more prisoners remain in captivity on either side.

Non-military actions taken by Armenia and Azerbaijan

Since the beginning of the conflict, both Armenia and Azerbaijan declared martial law, limiting the freedom of speech. Meanwhile, a new law came into effect since October 2020 in Armenia, which prohibits negative coverage of the situation at the front. Restrictions have been reported on the work of international journalists in Azerbaijan, with no corresponding restrictions reported in Nagorno-Karabakh.

Armenia

On 28 September 2020, Armenia banned men aged over 18 listed in the mobilisation reserve from leaving the country. The next day, it postponed the trial of former President Robert Kocharyan and other former officials charged in the 2008 post-election unrest case, owing to one of the defendants, the former Defence Minister of Armenia, Seyran Ohanyan, going to Artsakh during the conflict.

On 1 October 2020, the Armenian National Security Service (NSS) stated that it had arrested and charged a former high-ranking Armenian military official with treason on suspicion of spying for Azerbaijan. Three days later, the NSS stated that it had arrested several foreign citizens on suspicion of spying. Protesting Israeli arms sales to Azerbaijan, Armenia has recalled its ambassador to Israel.

On 8 October 2020, the Armenian President, Armen Sarkissian, dismissed the director of the NSS. Subsequently, the Armenian government toughened the martial law and prohibited criticising state bodies and "propaganda aimed at disruption of the defense capacity of the country". On the same day, the Armenian MoD cancelled ''a Novaya Gazeta'' correspondent's journalistic accreditation, officially for entering Nagorno-Karabakh without accreditation. On 9 October 2020, Armenia tightened its security legislation. On 21 October 2020, the Armenian Cabinet of Ministers temporarily banned the import of Turkish goods, the decision will come into force on 31 December 2020. The following day, the Armenian parliament passed a law to write off the debts of the Armenian servicemen wounded during the clashes and the debts of the families of those killed.

On 27 October 2020, the Armenian president Armen Sarkissian dismissed the head of the counterintelligence department of the National Security Service, Major General Hovhannes Karumyan and the chief of staff of the border troops of the National Security Service Gagik Tevosyan. On 8 November 2020, Sarkissian yet again dismissed the interim head of the National Security Service.

As of 8 November 2020, one Armenian activist was fined by the police for his anti-war post.

Azerbaijan

On 27 September 2020, Azerbaijani authorities restricted internet access shortly after the clashes began, stating it was "in order to prevent large-scale Armenian provocations." The government made a noticeable push to use Twitter, which was the only unblocked platform in the country. Despite the restrictions, some Azerbaijanis still used VPNs to bypass them. The National Assembly of Azerbaijan declared a curfew in Baku, Ganja, Goygol, Yevlakh and a number of districts from midnight on 28 September 2020, under the Interior Minister, Vilayet Eyvazov. Azerbaijan Airlines announced that all airports in Azerbaijan would be closed to regular passenger flights until 30 September 2020. The Military Prosecutor's Offices of Fuzuli, Tartar, Karabakh and Ganja began criminal investigations of war and other crimes.

Also on 28 September 2020, the President of Azerbaijan, Ilham Aliyev, issued a decree authorising a partial mobilisation in Azerbaijan. On 8 October 2020, Azerbaijan recalled its ambassador to Greece for consultations, following allegations of Armenians from Greece arriving in Nagorno-Karabakh to fight against Azerbaijan. Three days later, the Azerbaijani State Security Service (SSS) warned against a potential Armenian-backed terror attack.

On 17 October 2020, the Azerbaijani MoFA stated that member of the Russian State Duma from the ruling United Russia, Vitaly Milonov, was declared '' persona non grata'' in Azerbaijan for visiting Nagorno-Karabakh without permission from the Azerbaijani government. On 24 October 2020, by recommendation of the Central Bank of Azerbaijan, the member banks of the Azerbaijani Banks' Association unanimously adopted a decision to write off the debts of the military servicemen and civilians who died during the conflict.

On 29 October 2020, the President of Azerbaijan, Ilham Aliyev, issued a decree on the formation of temporary commandant's offices in the areas that the Azerbaijani forces seized control of during the conflict. According to the decree, the commandants will be appointed by the Ministry of Internal Affairs, but they will have to coordinate with other executive bodies of the government, including Ministry of Defense, the State Border Service, the State Security Service, and ANAMA.

By 31 October 2020, after gaining control of the territories on the border with Iran, Azerbaijan had established control over four more border posts.

By 4 November 2020, six peace activists from Azerbaijan have been called to questioning by the State Security Service, due to their anti-war activism in Azerbaijan.

On 12 December, a decree by President Aliyev lifted the curfew that had been imposed in September.

Casualties

Casualties have been high, officially in the low thousands. According to official figures released by the belligerents, Armenia lost 3,825 troops killed and 187 missing, while Azerbaijan lost 2,906 troops killed, with six missing in action. During the conflict, it was noted that the sides downplayed the number of their own casualties and exaggerated the numbers of enemy casualties and injuries.

Civilians

The Armenian authorities stated that 85 Armenian civilians were killed during the war, while another 21 were missing. According to Azerbaijani sources, the Armenian military has targeted densely populated areas containing civilian structures. As of 9 November 2020, the Prosecutor General's Office of the Republic of Azerbaijan stated that during the war, as a result of reported shelling by Armenian artillery and rocketing, 100 people had been killed, while 416 people had been wounded. Also, during the post-war clashes, the Azerbaijani authorities stated that an Azercell employee was seriously injured during the installation of communication facilities and transmission equipment near Hadrut.

As of 23 October 2020, the Armenian authorities has stated that the conflict had displaced more than half of Nagorno-Karabakh's population or approximately 90,000 people. The International Rescue Committee has also claimed that more than half of the population of Nagorno-Karabakh has been displaced by the conflict. As of 2 November 2020, the Azerbaijani authorities has stated that the conflict had displaced approximately 40,000 people in Azerbaijan.

Seven journalists have been injured. On 1 October 2020, two French journalists from ''Le Monde'' covering the clashes in Khojavend were injured by Azerbaijani shellfire. A week later, three Russian journalists reporting in Shusha were seriously injured by an Azerbaijani attack. On 19 October 2020, according to Azerbaijani sources, an Azerbaijani AzTV journalist received shrapnel wounds from Armenian shellfire in Aghdam District.

Military

Armenian authorities reported the deaths of 3,825 servicemen during the war, while the Azerbaijani authorities stated that more than 5,000 Armenian servicemen were killed, and several times more were wounded as of 28 October 2020. After the war, the former director of the Armenian National Security Service, Artur Vanetsyan, had also stated that some 5,000 Armenians were killed during the war. Also, the Armenian authorities had stated that about 60 Armenian servicemen were captured by Azerbaijan as prisoners of war. The former Head of the Military Control Service of the Armenian MoD, Movses Hakobyan, stated that already on the fifth day of war there were 1,500 deserters from Armenian armed forces, who were kept in Karabakh and not allowed to return to Armenia in order to prevent panic. The press secretary of Armenian prime minister called the accusations absurd and asked the law enforcement agencies to deal with them. Former military commissar of Armenia major-general Levon Stepanyan stated that the number of deserters in Armenian army was over 10,000, and it is not possible to prosecute such a large number of military personnel. During the post-war clashes, the Armenian government stated that 60 servicemen went missing, including several dozen that were captured. and On 27 October 2020, Artsakh authorities stated that its defence minister Jalal Harutyunyan was wounded in action. However, unofficial Azerbaijani military sources alleged that he was killed and released footage apparently showing the assassination from a drone camera.

During the conflict, the government of Azerbaijan did not reveal the number of its military casualties. On 11 January, Azerbaijan stated that 2,853 of its soldiers had been killed during the war, while another 50 went missing. Also, Azerbaijani authorities stated that 11 more Azerbaijani servicemen were killed during the post-war clashes or landmine explosions. On 23 October 2020, President of Azerbaijan, Ilham Aliyev, confirmed that Shukur Hamidov who was made National Hero of Azerbaijan in 2016, was killed during the operations in Qubadli District. This was the first military casualty officially confirmed by the government. However, Armenian and Artsakh authorities have claimed 7,630 Azerbaijani soldiers and Syrian mercenaries were killed.

The Syrian Observatory for Human Rights documented the death of at least 541 Syrian fighters or mercenaries fighting for Azerbaijan. On 14 November 2020, the Observatory reported the death of a commander of the Syrian National Army's Hamza Division.

Infrastructure damage

Civilian areas, including major cities, have been hit, including Azerbaijan's second-largest city, Ganja, and the region's capital, Stepanakert, with many buildings and homes destroyed. The Ghazanchetsots Cathedral has also been damaged. Several outlets reported increased cases of COVID-19 in Nagorno-Karabakh, particularly the city of Stepanakert, where the population was forced to live in overcrowded bunkers, due to Azerbaijan artillery and drone strikes conflict. There were also reported difficulties in testing and contact tracing during the conflict.

The Ghazanchetsots Cathedral in Shusha became damaged as a result of shelling. On 19 October 2020, a strong fire broke out in a cotton plant in Azad Qaraqoyunlu, Tartar District, as a result of the Armenian artillery shelling, with several large hangars of the plant becoming completely burned down. An Armenian-backed Nagorno-Karabakh human rights ombudsman report noted 5,800 private properties and 520 private vehicles destroyed, with damage to 960 items of civilian infrastructure, and industrial and public and objects. On 16 November 2020, the Prosecutor General's Office of the Republic of Azerbaijan reported 3,410 private houses, 512 civilian facilities, and 120 multi-storey residential buildings being damaged throughout the war.

Equipment losses

By 7 October 2020, Azerbaijan reported to have destroyed about 250 tanks and other armoured vehicles; 150 other military vehicles; 11 command and command-observation posts; 270 artillery units and MLRSs, including a BM-27 Uragan; 60 Armenian anti-aircraft systems, including 4 S-300 and 25 9K33 Osas; 18 UAVs and 8 arms depots. destroyed. As of 16 October 2020, the Azerbaijani President stated that the Armenian losses were at US$2 billion. In turn an Azerbaijani helicopter was stated to have been damaged, but its crew had apparently returned it to Azerbaijani-controlled territory without casualties. Later it was reported that on 12 October 2020, Azerbaijan had destroyed one Tochka-U missile launcher. On 14 October 2020, Azerbaijan stated it had further destroyed five T-72 tanks, three BM-21 Grad rocket launchers, one 9K33 Osa missile system, one BMP-2 vehicle, one KS-19 air defence gun, two D-30 howitzers and several Armenian army automobiles. On the same day, Azerbaijan announced the destruction of three R-17 Elbrus tactical ballistic missile launchers that had been targeting Ganja and Mingachevir. BBC reporters confirmed the destruction of at least one tactical ballistic missile launcher in the vicinity of Vardenis, close to the border with Azerbaijan, and posted photo evidence in support of this information. Later American journalist Josh Friedman posted a high quality video of a destroyed Armenian ballistic missile launcher.

Armenian and Artsakh authorities initially reported the downing of four Azerbaijani helicopters and the destruction of ten tanks and IFVs, as well as 15 drones. Later the numbers were revised to 36 tanks and armoured personnel vehicles destroyed, two armoured combat engineering vehicles destroyed and four helicopters and 27 unmanned aerial vehicles downed all within the first day of hostilities. They released footage showing the destruction or damage of five Azerbaijani tanks. Over the course of 2 October, the Artsakh Defence Army said they had destroyed 39 Azerbaijani military vehicles, including a T-90 tank; four SU-25 fighter-bombers; three Mi-24 attack helicopters; and 17 UAVs.

According to Dutch warfare research group Oryx, which documents visually confirmed losses on both sides, Armenia lost 255 tanks (destroyed: 146, damaged: 6, captured: 103), 78 armoured fighting vehicles (destroyed: 25, damaged: 1, captured: 52), and 737 trucks, vehicles and jeeps (destroyed: 331, damaged: 18, captured: 387), while Azerbaijan lost 62 tanks (destroyed: 38, damaged: 16, abandoned: 1, captured: 7, captured but later lost: 1), 23 armoured fighting vehicles (destroyed: 6, damaged: 3, abandoned: 7, captured: 9), 76 trucks, vehicles and jeeps (destroyed: 40, damaged: 22, abandoned: 8, captured: 6), as well 11 old An-2 aircraft, used as unmanned bait in order for Armenia to reveal the location of air defence systems. Oryx only counts destroyed vehicles and equipment of which photo or videographic evidence is available, and therefore, the actual number of equipment destroyed is higher.

Suspected war crimes

UN Secretary-General António Guterres stated that "indiscriminate attacks on populated areas anywhere, including in Stepanakert, Ganja and other localities in and around the immediate Nagorno-Karabakh zone of conflict, were totally unacceptable". Amnesty International stated that both Azerbaijani and Armenian forces committed war crimes during recent fighting in Nagorno-Karabakh, and called on Azerbaijani and Armenian authorities to immediately conduct independent, impartial investigations, identify all those responsible, and bring them to justice.

Azerbaijan started an investigation on war crimes by Azerbaijani servicemen in November and as of 14 December, has arrested four of its servicemen.

Armenian

Armenia struck several Azerbaijani cities outside of the conflict zone, most frequently Tartar, Beylagan and Barda. Attacks reported by Azerbaijani authorities included an attack on Beylagan on 4 October, killing two civilians and injuring 2 others, Goranboy on 8 October killing a civilian, Hadrut on 10 October, seriously injuring a medical worker, Fuzuli on 20 October, resulting in one civilian death and six injuries, Tartar on 20 October, resulting in two civilian deaths and one civilian injury and Tartar on 10 November, resulting in one civilian injury. By 9 November, there had been more than 93 civilian deaths and 416 civilian injuries in areas of Azerbaijan outside of the war zone.

Human Rights Watch reported that on 27 September, the Armenian forces had launched an artillery attack on Qaşaltı of Goranboy District, killing five members of the Gurbanov family, and damaged several homes. Human Rights Watch examined the severely damaged house and found several munition remnants in the courtyard that were consistent with fragments of large-caliber artillery. It also reported that the Armenian forces struck Hacıməmmədli of Aghdam District on 1 October, in an agricultural area, at around 11:00, killing two civilians. HRW stated that they had found no evident military objectives during their visit to the village. HRW also reported that the Armenian forces had launched an artillery attack on 4 October in Tap Qaraqoyunlu of Goranboy District at about 16:30, wounding a civilian. Then, on 5 October, Human Rights Watch reported that the Armenian forces fired a munition that landed in a field about 500 meters from Babı of Fuzuli District. The Azerbaijani authorities stated that they had identified the munition as a Scud-B ballistic missile and measured the crater as 15 meters in diameter.

Armenian forces heavily shelled the district of Tartar during the war, starting from 28 September. The bombardment caused widespread destruction and many civilian deaths. Thousands of people became refugees, making the city of Tartar a ghost town, and fled to neighbouring cities such as Barda. The Azerbaijani authorities stated that the Armenian forces had fired 15,500 shells on the territory of Tartar District until 29 October, with over 2,000 shells being fired upon Tartar in some days. Official Azerbaijani figures show that over a thousand civilian objects, including schools, hospitals, and government buildings were either damaged or destroyed during the bombardment. Human Rights Watch confirmed many of the targeted attacks on civilians and civilian objects, such as kindergartens and hospitals, by the Armenian forces. It also stated that the Armenian military forces had carried out unlawfully indiscriminate rocket and missile strikes on the Azerbaijani territories, and that such indiscriminate attacks were war crimes. The constant bombardment of the city prompted the Azerbaijani to label Tartar as the '' Stalingrad of Azerbaijan'', and the President of Azerbaijan, Ilham Aliyev, accused Armenia of trying to turn Tartar to the next Aghdam, also referred to as the '' Hiroshima of the Caucasus'' by the locals. Turkey also condemned the Armenian shelling of a cemetery in Tartar during a funeral ceremony, which foreign journalists at scene and Human Rights Watch confirmed. On 29 October, the head of the Tartar District Executive Power, Mustagim Mammadov, stated that during the war, 17 civilians killed, and 61 people injured in Tartar District as a result of the bombardment in Tartar. According to him, in total, about 1,200 people suffered from the bombardment. The Azerbaijani authorities reported two more civilian injuries later on.

Between 4 and 17 October, four separate missile attacks on the city of Ganja killed 32 civilians, including a 13-year-old Russian citizen, and injured 125 with women and children among the victims. The attacks were condemned by the European Union, and Azerbaijani authorities accused the Armenian Armed Forces of "committing war crimes through the firing of ballistic missiles at civilian settlements", calling the third attack "an act of genocide". Armenia denied responsibility for the attacks. The Artsakh Defence Army confirmed responsibility for the first attack but denied targeting residential areas, claiming that it had fired at military targets, especially Ganja International Airport. Subsequently, both a correspondent reporting from the scene for a Russian media outlet and the airport director denied that the airport had been hit, while a ''BBC News'' journalist, Orla Guerin, visited the scene and found no evidence of any military target there.

On 15 October, the Armenian forces shelled a cemetery north of the city of Tartar during a funeral ceremony, killing 4 civilians and injuring 4 more. This was confirmed by local journalists, ''Dozhd'', and the Human Rights Watch. The Presidential Administration of Azerbaijan also confirmed that the cemetery was shelled in the morning.

On 25 October, a video emerged online of an Armenian teenager in civilian clothing helping soldiers fire artillery on Azerbaijani positions. Azerbaijan subsequently accused Armenia of using child soldiers. One day later, the Artsakh ombudsman released a statement claiming that the boy in the video was 16, was not directly engaged in military actions and was working with his father.

The Human Rights Watch reported that on 28 October, at about 17:00, the Armenian forces fired a munition on Tap Qaraqoyunlu of Goranboy District that produced fragmentation and killed a civilian.

The Artsakh Defence Army hit the Azerbaijani town of Barda with missiles twice on 27 and 28 October 2020, resulting in the deaths of 26 civilians and injuring over 83, making it the deadliest attack of the conflict. The casualties included a 39-year-old Red Crescent volunteer, while two other volunteers were injured. Civilian infrastructure and vehicles were extensively damaged. Armenia denied responsibility, but Amnesty International and Human Rights Watch stated that Armenia had fired, or intentionally supplied Artsakh with, the cluster munitions and Smerch rockets used in the attack. Artsakh acknowledged responsibility, but said it was targeting military facilities. Marie Struthers, Amnesty International's Regional Director for Eastern Europe and Central Asia, said that the "firing of cluster munitions into civilian areas is cruel and reckless, and causes untold death, injury and misery". The Azerbaijani ombudsman called the attack a "terrorist act against civilians". The use of cluster munitions was also reported by ''The New York Times''. On 7 November, according to Human Rights Watch, the Armenian forces fired a rocket that struck an agricultural field near the village of Əyricə and killed a 16-year-old boy while he playing with other children. Azerbaijani authorities stated that they had identified the munition as a 9M528 Smerch rocket, which carries a warhead that produces blast and fragmentation effect. HRW reported that the researchers did not observe any military objectives in the area.

On 30 October 2020, Human Rights Watch reported that Armenia or Artsakh forces used cluster munition and stated that Armenia should immediately cease using cluster munitions or supplying them to Nagorno-Karabakh forces.

In mid-November, a video of a wounded Azerbaijani soldier Amin Musayev receiving first aid by Ukrainian journalist Alexander Kharchenko and Armenian soldiers after the ceasefire came into force was spread on social media platforms. Following this, a video was released showing Musayev being abused inside a vehicle. It is reported that he was lying on the ground in the car and asked: "where are we going?" In response, the alleged Armenian soldier said, "If you behave well, go home," and cursed, after which it became clear that the Azerbaijani soldier had been kicked. On 18 November, a representative of the International Committee of the Red Cross (ICRC) in Yerevan said that information about this person was "being investigated." The ICRC's representative in Yerevan, Zara Amatuni, declined to say whether she had any information about Musayev. The Artsakh ombudsman said he had no information about the Azerbaijani soldier, but that if he was injured, he was "probably in hospital in Armenia." The Azerbaijani Foreign Ministry said in a statement that the issue was being investigated and will be reported to the relevant international organisations. According to the ministry, "the information about the torture of prisoners is first checked for accuracy and brought to the attention of relevant international organizations." On 25 November, ICRC's representatives visited Musayev and Karimov in Yerevan. On 5 December, the family of Musayev was informed of his condition through ICRC. According to a reported copy of the letter sent by Musayev, he stated that his condition was well. Musayev was returned to Azerbaijan on 15 December as part of the POW exchange deal. Azerbaijan had officially accused the Armenian side of ill-treating the Azerbaijani POWs. Several Azerbaijani POWs, in interviews with the Azerbaijani media outlets, had stated that they were tortured by their Armenian captors until being transferred back to Azerbaijan. Dilgam Asgarov, a Russian citizen of Azerbaijani descent, who was detained by the Armenian-allied forces alongside Shahbaz Guliyev, an Azerbaijani citizen, in 2014, during an incident in Kalbajar, in an interview to ''Virtual Azərbaycan'' newspaper he gave after being released, also stated that the Armenian captors had tortured the Azerbaijani POWs.

On 10 December, Amnesty International released a report on videos depicting war crimes. In one of the videos, the Armenian soldiers were seen cutting the throat of an Azerbaijani captive. The captive appears to be lying on the ground, whilst gagged and bound when an Armenian soldier approaches him and sticks a knife into his throat. Independent pathological analysis confirmed that the wound sustained led to his death in minutes. Eleven other videos showing inhumane treatment and outrages upon personal dignity of Azerbaijani captives by the Armenian army has come to light. In several videos, Armenian soldiers are seen cutting the ear off a dead Azerbaijani soldier, dragging a dead Azerbaijani soldier across the ground by a rope tied around his feet, and standing on the corpse of a dead Azerbaijani soldier.

On 11 December, Human Rights Watch released an extensive report about Armenia's unlawful rocket strikes on Azerbaijani civilian areas. The report investigated 18 separate strikes, which killed 40 civilians and wounded dozens more. During on-site investigations in Azerbaijan in November, Human Rights Watch documented 11 incidents in which Armenian forces used ballistic missiles, unguided artillery rockets, large-calibre artillery projectiles and cluster munitions that hit populated areas in apparently indiscriminate attacks. In at least four other cases, munitions struck civilians or civilian objects in areas where there were no apparent military targets. In addition to causing civilian casualties, the Armenian attacks damaged homes, businesses, schools, and a health clinic, and contributed to mass displacement. It acknowledged the presence of military forces in two cities and two villages attacked by Armenian forces, claiming that Azerbaijan had unnecessarily put civilians at risk, however, it also stated that the presence of military targets did not excuse the use of inherently inaccurate weaponry with a large destructive radius in populated areas by Armenian forces. Human Rights Watch called the Armenian government to conduct transparent investigations into attacks by Armenian forces that violate international humanitarian law, or the laws of war. On 15 December, Human Rights Watch released another report about Armenia's use of cluster munitions in multiple attacks on Azerbaijani civilian areas. Its researchers documented four attacks with cluster munitions in three of the country's districts, Barda, Goranboy and Tartar which killed at least seven civilians, including two children, and wounded close to 20, including two children. Human Rights Watch also stated that as Nagorno-Karabakh forces do not possess cluster munitions, it is likely that Armenian forces carried out the attacks or supplied the munitions to Nagorno-Karabakh forces.

On 4 October 2020, the Armenian government stated Azerbaijan had deployed cluster munitions against residential targets in Stepanakert; an Amnesty International investigator condemned this. In an Amnesty International report, the cluster bombs were identified as "Israeli-made M095 DPICM cluster munitions that appear to have been fired by Azerbaijani forces". The next day, Armenian Minister of Foreign Affairs Zohrab Mnatsakanyan stated to Fox News that the targeting of civilian populations in Nagorno-Karabakh by Azerbaijani forces was tantamount to war crimes and called for an end to the "aggression". In November 2020, Aliyev denied using cluster munitions against civilian areas in Stepanakert on the 1, 2, and 3 October 2020 in an interview with ''BBC News'' journalist Orla Guerin, describing as "fake news" the statements of other BBC reporters who witnessed the attacks and described them as "indiscriminate shelling of a town without clear military targets".

During an on-site investigation in Nagorno-Karabakh in October 2020, Human Rights Watch documented four incidents in which Azerbaijan used Israeli-supplied cluster munitions against civilian areas of Nagorno-Karabakh. The HRW investigation team stated that they did not find any sort of military sites in the residential neighbourhoods where the cluster munitions were used and condemned its use against civilian-populated areas. Stephen Goose, arms division director at Human Rights Watch and chair of the Cluster Munition Coalition, stated that "the continued use of cluster munitions – particularly in populated areas – shows flagrant disregard for the safety of civilians". He then added that "the repeated use of cluster munitions by Azerbaijan should cease immediately as their continued use serves to heighten the danger for civilians for years to come". The HRW investigation team also noted that numerous civilian buildings and infrastructure were heavily damaged due to shelling.

On 16 December, Human Rights Watch published a report about two separate attacks, hours apart, on the Ghazanchetsots Cathedral on 8 October in the town of Shusha, known to Armenians as Shushi, suggesting that the church, a civilian object with cultural significance, was an intentional target despite the absence of evidence that it was used for military purposes. The weapon remnants Human Rights Watch collected at the site corroborate the use of guided munitions. "The two strikes on the church, the second one while journalists and other civilians had gathered at the site, appear to be deliberate," said Hugh Williamson, Europe and Central Asia director at Human Rights Watch. "These attacks should be impartially investigated and those responsible held to account."

On 15 October 2020, a video surfaced of two captured Armenians being executed by Azerbaijani soldiers; Artsakh authorities identified one as a civilian. ''Bellingcat'' analysed the videos and concluded that the footage was real and that both executed were Armenian combatants captured by Azerbaijani forces between 9 and 15 October 2020 and later executed.
