Evidence of the attack

Inspectors from the United Nations Mission already in Syria to investigate an earlier alleged chemical weapons attack requested access to sites in Ghouta the day after the attack and called for a ceasefire to allow inspectors to visit the Ghouta sites. The Syrian Ba'athist government granted the UN's request on 25 August, and inspectors visited and investigated Moadamiyah in Western Ghouta the next day and Zamalka and Ein Tarma in Eastern Ghouta on 28 and 29 August. The UN investigation team confirmed "clear and convincing evidence" of the use of sarin delivered by surface-to-surface rockets, and a 2014 report by the

The evidence available concerning the nature, quality and quantity of the agents used on 21 August indicated that the perpetrators likely had access to the chemical weapons stockpile of the Syrian military, as well as the expertise and equipment necessary to safely manipulate large amount of chemical agents." It also stated that the chemical agents used in the Khan al-Assal chemical attack earlier in 2013 "bore the same unique hallmarks as those used in Al-Ghouta".

operation by the opposition to draw foreign powers into the civil war on the rebels' side. Åke Sellström, the leader of the UN Mission, characterized government explanations of rebel chemical weapons acquisition as unconvincing, resting in part upon "poor theories". Several countries including France, the United Kingdom and the United States debated whether to intervene militarily against Syrian Ba'athist government forces. On 6 September 2013, the United States Senate filed a resolution to authorize use of military force against the Syrian military in response to the Ghouta attack. On 10 September 2013, the military intervention was averted when the Syrian government accepted a US–Russian negotiated deal to turn over "every single bit" of its chemical weapons stockpiles for destruction and declared its intention to join the

Background

The Ghouta area is composed of densely populated suburbs to the east and south of

, part of the province of Rif Dimashq. Ghouta is a primarily conservative Sunni region. Since early in the civil war, civilians in rebel-held Eastern Ghouta almost entirely sided with the opposition to Syria's government. The opposition had controlled much of Eastern Ghouta since 2012, partly cutting off Damascus from the countryside. Muadamiyat al-Sham in Western Ghouta had been under government siege since April 2013. Ghouta had been the scene of continuing clashes for more than a year before the chemical attack, with government forces launching repeated missile assaults trying to dislodge the rebels. The week of the attack, the Syrian government launched an offensive to capture opposition-held Damascus suburbs. The attack came one year and one day after US President

That would change my calculus. That would change my equation." Syria was one of five non-signatories to the 1997

at the time. After the "red line" remarks, and before the chemical attack in Ghouta, chemical weapons were suspected to have been used in four attacks in the country.

Khan al-Assal chemical attack

The Khan al-Assal chemical attack occurred on 19 March 2013, when a government-controlled area of Khan al-Asal, a district of

the attack resulted in at least 26 fatalities, including 16 government soldiers and 10 civilians. The Syrian government later reported to the United Nations that one soldier and 19 civilians died and that 17 soldiers and 107 civilians were injured. A medic at the local civilian hospital said he personally had witnessed Syrian army soldiers helping the wounded and dealing with fatalities at the scene. It was later found that the sarin used in the Khan al-Assal attack "bore the same unique hallmarks" as the sarin used in the Ghouta attack.

established the Independent International Commission of Inquiry on the Syrian Arab Republic on 22 August 2011 to investigate human rights violations during the Syrian civil war. One of the topics the commission investigated was possible use of chemical weapons. In early June 2013, the Fifth Report of the Commission of Inquiry stated that there were reasonable grounds to believe that toxic chemicals were used in four attacks, but more evidence was needed "to determine the precise chemical agents used, their delivery systems or the perpetrator". On 22 June, the head of the Commission of Inquiry, Paulo Pinheiro, said the UN could not determine who used chemical weapons in Syria based on evidence sent by the United States, Britain and France.

Rhodes stated: "The president has said that the use of chemical weapons would change his calculus, and it has." The French government announced that its own tests confirmed US assertions.

Russian assessment

Russian Foreign Minister Sergei Lavrov said "the accusations of Damascus using chemical weapons put forth by the United States are not backed by credible facts". Lavrov further stated that the Syrian government had no motive to use chemical weapons since the government already maintained a military advantage over the rebel fighters.

One (or both) of the labs examining the environmental samples taken from Zamalka (and Ein Tarma) found at least traces of sarin in 14 of the 17 cases. One of the labs described the sarin level as a "high level concentration" in 4 of the 17 samples.

Western Ghouta attack

The second attack took place in the Western Ghouta area around 5:00 in the morning on 21 August. On 22 August, a witness who works for Moadamiya media center said he had counted seven rockets that fell in two areas of Moadamiya during the early morning of 21 August. He said four rockets hit next to the Rawda Mosque and another three in the area between Qahweh Street and Zeytouneh Street, which he said was approximately 500 meters to the east of the Rawda Mosque. He said all the rockets were of the same type. While no chemical warhead was ever found in the Western Ghouta area, one rocket engine has been identified as a 140mm M-14 unguided surface-to-surface rocket. This type of rocket can be fitted with three types of warheads: high explosive-fragmentation, white phosphorus smoke, or a chemical warhead containing of sarin. None of the 13 environmental samples taken from Western Ghouta tested positive for sarin, although three had "degradation and/or by-products".

In 2012 Syria publicly stated it possessed chemical and biological weapons and would use them if it faced a foreign attack. According to French intelligence, the Syrian Scientific Studies and Research Center (SSRC) is responsible for producing toxic agents for use in war. A group named "Branch 450" is allegedly responsible for filling munitions with chemicals and maintaining security of the chemical agent stockpiles. As of September 2013, French intelligence estimated the Syrian stockpile at 1,000 tonnes, including

, VX and "several hundred tonnes of sarin". The UK's Joint Intelligence Committee publicly dismissed the possibility of rebel responsibility for the attack in Ghouta, stating that rebels are incapable of an attack of its scale. The Committee stated that "there is no credible intelligence or evidence to substantiate the claims or the possession of CW by the opposition". Åke Sellström, a Swedish scientist who led the UN mission to investigate the attacks, said it was difficult to see how rebels could have weaponized the toxins, but admitted that he did not know who the perpetrator was. According to the Associated Press, "chemical and biological weapons experts have been relatively consistent in their analysis, saying only a military force with access to and knowledge of missile delivery systems and the sarin gas suspected in Ghouta could have carried out an attack capable of killing hundreds of people."

Initial claims

Both the opposition and the Syrian government said a chemical attack was carried out in the suburbs around Damascus on 21 August 2013. Anti-government activists said the Syrian government was to blame for the attack, while the Syrian government said foreign fighters and their international backers were to blame.

Opposition claims

On the day of the attack, George Sabra, the head of the Syrian National Council, said 1,300 people had been killed as shells loaded with poisonous gas rained down on the capital's eastern suburbs of Douma, Jobar, Zamalka, Arbeen and Ein Tarma. A spokesman for the Free Syrian Army's Supreme Military Council, Qassim Saadeddine, said, "people are growing desperate as they watch another round of political statements and UN meetings without any hope of action". Ahmad Jarba, who was the president of the Syrian National Coalition at the time of the attack, called on the UN investigators to travel to "the site of the massacre" and for an urgent

officials were convinced that the Syrian government was trying to hide the evidence of chemical weapons use by shelling the sites and delaying their inspection. Ban called for a ceasefire to allow the inspectors to visit the attack sites. On 25 August the government and various rebel factions agreed to a ceasefire for five hours each day from 26 to 29 August. Early in the morning of 26 August several mortars hit central Damascus, including one that fell near the Four Seasons Hotel where the UN inspectors were staying. Later in the day the UN team came under sniper fire en route to Moadamiyah in western Ghouta (to the southwest of central Damascus), forcing them to return to their hotel and replace one of their vehicles before continuing their investigation four hours later. The attack prompted a rebuke from Ban toward the fighters. After returning to Moadamiyah the UN team visited clinics and makeshift field hospitals, collected samples and conducted interviews with witnesses, survivors and doctors. The inspectors spoke with 20 victims of the attacks and took blood and hair samples, soil samples, and samples from domestic animals. As a result of the delay caused by the sniper attack, the team's time in Moadamiyah was substantially shortened, with the scheduled expiry of the daily cease-fire leaving them around 90 minutes on the ground. On 28 and 29 August the UN team visited Zamalka and Ein Tarma in Eastern Ghouta, east of central Damascus, for a total time of five-and-a-half hours. On 30 August the team visited a Syrian government military hospital in Mazzeh and collected samples. The mission left Syria early on 31 August, over the objection of the Syrian government, promising to return to complete the original objective to investigate the previously alleged attack sites.

UN Ghouta Area report

The UN report on the investigation into the Ghouta chemical attacks was published on 16 September 2013. The report stated: "the environmental, chemical and medical samples we have collected provide clear and convincing evidence that surface-to-surface rockets containing the nerve agent sarin were used in Ein Tarma, Moadamiyah and Zamalka in the Ghouta area of Damascus." UN Secretary-General Ban Ki-moon called the findings "beyond doubt and beyond the pale", and clear evidence of a war crime. "The results are overwhelming and indisputable", he said. Ban stated a majority of the blood samples, environmental samples and rockets or rocket fragments recovered tested positive for sarin. The report, which was "careful not to blame either side", said that during the mission's work in areas under rebel control, "individuals arrived carrying other suspected munitions indicating that such potential evidence is being moved and possibly manipulated". The UN investigators were accompanied by a rebel leader: The British UN Ambassador stated that the report's lead author, Åke Sellström, said the quality of the sarin used in the attack was higher than that used by Iraq in the

Final UN Mission report

The UN inspection team returned to Syria to continue investigations into other alleged chemical attacks in late September 2013. A final report on Ghouta and six other alleged attacks (including three alleged to have occurred after the Ghouta attack) was released in December 2013. The inspectors wrote that they "collected clear and convincing evidence that chemical weapons were used also against civilians, including children, on a relatively large scale in the Ghouta area of Damascus on 21 August 2013". The conclusion was based on: * Impacted and exploded surface-to-surface rockets, capable to carry a chemical payload, were found to contain sarin; * Close to the rocket impact sites, in the area where patients were affected, the environment was found to be contaminated by sarin; * The epidemiology of over fifty interviews given by survivors and health care workers provided ample corroboration of the medical and scientific results; * A number of patients/survivors were clearly diagnosed as intoxicated by an organophosphorous compound; * Blood and urine samples from the same patients were found positive for sarin and sarin signatures.

UN Human Rights Council report

The 7th Report of the Independent International Commission of Inquiry on the Syrian Arab Republic, a different group than the UN fact-finding mission, stated the sarin used in the Ghouta attack bore the "same unique hallmarks" as the sarin used in the Khan al-Assal attack. The report, dated 12 February 2014, also indicated that the perpetrators likely had access to the chemical weapons stockpile of the Syrian military. These conclusions were based on the fact-finding mission's evidence, as the Commission of Inquiry did not conduct its own investigation of either chemical attack.

Aftermath

The continuous fighting has severely limited the quality of medical care for injured survivors of the attack. A month after the attack, approximately 450 survivors still required medical attention for lingering symptoms such as respiratory and vision problems. By early October 2013, the 13,000 residents of Moadhamiya, one of the places targeted in the August attack, had been surrounded by pro-government forces and under siege for five months. Severe malnourishment and medical emergencies had become pressing as all supply lines had stopped. Care for chronic symptoms of sarin exposure had become "just one among a sea of concerns". As countries such as the United States and the United Kingdom debated their response to the attacks, they encountered significant popular and legislative resistance to military intervention. In particular, British Prime Minister David Cameron's request to the House of Commons to use military force was declined by a 285–272 margin. UK government policy subsequently focused on providing humanitarian assistance inside Syria and to refugees in neighboring countries. Within a month of the attacks, Syria agreed to join the

supervision on 6 October 2013. On 23 June 2014, the last shipment of Syria's declared chemical weapons was shipped out of the country for destruction. By 18 August 2014, all toxic chemicals were destroyed aboard the US naval vessel MV ''Cape Ray''. Nine months after the attack, there was evidence that mothers from the affected areas were giving birth to children with defects and as stillborn.

on an alternative proposal, under which Syria would declare and surrender its chemical weapons to be destroyed under international supervision. In contrast to the positions of their governments, polls in early September indicated that most people in the US, UK, Germany and France opposed military intervention in Syria. One poll indicated that 50% of Americans could support military intervention with cruise missiles only, "meant to destroy military units and infrastructure that have been used to carry out chemical attacks". In a survey of American military personnel, around 75% said they opposed air strikes on Syria, with 80% saying an attack would not be "in the U.S. national interest".

Allegations of false flag attack

The attacks prompted some U.S. intelligence officials to speculate they were carried out by the opposition in order to draw the West into the war, a concept dismissed by others.

In the article, Hersh related that a former senior U.S. intelligence official told him that the U.S. government's published assessment of the incident included an account of the sequence the Syrian military would have followed for any chemical attack, rather than intercepts specifically relating to the Ghouta attacks. In April 2014 Hersh wrote an article, also published by the LRB, reporting that a former intelligence officer told him that the attacks were "covert action planned by Erdoğan's people to push Obama over the red line", speculating about Turkish government support for

Analysis of symptoms

Dr. Amesh Adalja, a then-senior associate for the Center for Biosecurity at the University of Pittsburgh Medical Center, said the reported symptoms are a textbook case of nerve-agent poisoning.

director of operations Bart Janssens stated that MSF "can neither scientifically confirm the cause of these symptoms nor establish who is responsible for the attack. However, the reported symptoms of the patients, in addition to the epidemiological pattern of the events – characterised by the massive influx of patients in a short period of time, the origin of the patients, and the contamination of medical and first aid workers – strongly indicate mass exposure to a neurotoxic agent." Gwyn Winfield, editorial director at ''CBRNe World'', analysed some videos from the day of the attack and wrote on the magazine's website: "It is difficult to define nagent by the signs and symptoms. Clearly respiratory distress, some nerve spasms and a half-hearted washdown (involving water and bare hands?!), but it could equally be a riot control agent as a hemical warfare agent"

Rockets

HRW also reported that at the time of the attack, Syrian rebels were not known to be in possession of the rockets used. Seymour Hersh has suggested that the 330mm rockets may have been produced locally, and with a limited range. Eliot Higgins has looked at the munitions linked to the attack and analysed footage of the putative launchers inside government territory.

, the rockets used in the attack had a range of about two kilometers, which, the authors claimed, meant that the munitions could not have been fired from the 'heart' or from the Eastern edge of the Syrian Government Controlled Area shown in the Intelligence Map published by the White House on 30 August 2013. A response from Higgins and Kaszeta included an observation that the Russian-language news site ANNA News had posted videos showing a Syrian government military operation running from June to August 2013 to clear positions between Jobar and Qaboun, a strip of land about 2 km away from 21 August impact sites. Many of the munitions and their fragments had been moved; however, in two cases, the UN could identify the likely launch azimuths. Triangulating rocket trajectories suggests that the origin of the attack may have been within government or rebel-held territory. Consideration of missile ranges influences calculations as to whether rockets originated from the government or rebel-held regions.

Communications

reported that, according to two U.S. intelligence officials and two other U.S. officials, the U.S. intercept was a conversation between "low-level" Syrian officials with no direct link to the upper echelons of the government or military. The '' Bild am Sonntag'' newspaper subsequently reported that German intelligence indicated that Assad had likely not ordered the attacks. According to ''Bild'', "intelligence interception specialists" relying on communications intercepted by the German vessel ''Oker'' said that Syrian military commanders had repeatedly been asking permission to launch chemical attacks for around four months, with permission always being denied from the presidential palace.

Almost all the journalists died from inhalation of the neurotoxins, except Murad Abu Bilal, who was the only Zamalka LCC media member to survive. The videos were published on YouTube, attracting worldwide media attention. Experts who have analysed the first video said it shows the strongest evidence yet consistent with the use of a lethal toxic agent.

, said the footage showed what a chemical weapons attack on a civilian area would look like, and went on to note "This is one of the first videos I've seen from Syria where the numbers start to make sense. If you have a gas attack you would expect large numbers of people, children and adults, to be affected, particularly if it's in a built-up area." Some experts, among them Jean Pascal Zanders, initially stated that evidence that sarin was used, as claimed by pro-rebel sources, was still lacking and highlighted the lack of second-hand contaminations typically associated with use of weapons-grade nerve agents: "I remain sceptical that it was a nerve agent like sarin. I would have expected to see more convulsions", he said. "The other thing that seems inconsistent with sarin is that, given the footage of first responders treating victims without proper protective equipment, you would expect to see considerable secondary casualties from contamination – which does not appear to be evident." However, after Zanders saw footage imminently after the attack, he changed his mind, saying: "The video footage and pictures this time are of a far better quality. You can clearly see the typical signs of asphyxiation, including a pinkish blueish tinge to the skin colour. There is one image of an adult woman where you can see the tell-tale blackish mark around her mouth, all of which suggests death from asphyxiation." Zanders however cautioned that these symptoms covered a range of neurotoxicants, including some available for civilian use as pest control agents, and said that until the UN reported its analysis of samples, "I can't make a judgement. I have to keep an open mind." According to a report by ''

Foreign government assessments

was most likely responsible for the attacks. Western intelligence agencies agreed that video evidence is consistent with the use of a nerve agent, such as sarin. Laboratory tests showed traces of sarin, in blood and hair samples collected from emergency workers who responded to the attacks. Russia said there was no evidence tying the Syrian government to the attack and that it was likely carried out by an opposition group.

France

On 2 September, the French

A report on the attacks by the United Kingdom's Joint Intelligence Committee (JIC) was published on 29 August 2013 prior to a vote on intervention by the

. The report said at least 350 people were killed and that it was "highly likely" that the attacks had been carried out by the Syrian government, resting in part on the firm view that the Syrian opposition was not capable of carrying out a chemical weapons attack on this scale, and on the JIC view that the Syrian government had used chemical weapons in the Syrian civil war on a small scale on 14 previous occasions. Analysis of the Ghouta attacks themselves was based largely on reviewing video footage and publicly available witness evidence. The report conceded problems with motivation for the attacks, saying there was "no obvious political or military trigger for regime use of CW on an apparently larger scale now". British officials said they believe the Syrian military used chemical weapons, including the nerve agent sarin, on a small scale against the opposition on at least 14 times prior to the Ghouta attacks and described "a clear pattern of regime use" of the nerve agent since 2012.

It dismissed the possibility that evidence supporting the US government's conclusion could have been manufactured by the opposition, stating it "does not have the capability" to fabricate videos, eyewitness accounts, and other information. The report also said that the US believed Syrian officials directed the attacks, based on "intercepted communications". A major element, as reported by news media, was an intercepted telephone call between a Syrian Ministry of Defense official and a Syrian 155th Brigade chemical weapons unit commander in which the former demanded answers for the attacks. According to some reports, this phone intercept was provided to the U.S. by Israeli Intelligence Corps

Grayson cited as a problematic example the intercepted phone call between a Syrian Ministry of Defense official and the Syrian 155th Brigade, the transcript of which was not provided in the classified report, leaving Grayson unable to judge the accuracy of a report in The Daily Caller that the call's implications had been misrepresented in the report.

In other words, under its current obligations Syria is forbidden from using gas against its neighbours but not against its own people.

International Criminal Court referral

Human Rights Watch stated that the

should refer the Syria situation to the

Amnesty International Amnesty International (also referred to as Amnesty or AI) is an international non-governmental organization focused on human rights, with its headquarters in the United Kingdom. The organization says that it has more than ten million members a ...

also said that the Syria situation should be referred to the ICC because "the best way for the United States to signal its abhorrence for war crimes and crimes against humanity and to promote justice in Syria, would be to reaffirm its support for the Rome Statute establishing the International Criminal Court". However, as the amendment to the Rome Statute of the International Criminal Court explicitly making it a war crime to use chemical weapons in an internal conflict has not been ratified by most states nor Syria, the legal situation is complex and reliant on the attack being a part of a wider war crime. China and Russia have repeatedly used their status as members of the U.N. Security Council to block any attempt to bring Syria under the jurisdiction of the ICC; by 2017, Russia had used its veto power at least seven times to prevent the U.N. Security Council from taking action.

Legal investigations in Germany, France, and Sweden

After Russia and China blocked attempts to set up an international tribunal for Syria, survivors of the attack and human rights organizations have taken legal action in France, Germany, and Sweden. In October 2020, three human rights organizations submitted, on behalf of the victims of the attack, a criminal complaint and a dossier of evidence to Germany's federal public prosecutor in

; the dossier includes testimony from at least 17 survivors of the attack and 50 defectors from the Syrian government with knowledge of the government's chemical weapons program or plans to carry out chemical attacks in Ghouta and Khan Shaykhun. In February 2021, lawyers representing victims of the attack and two international human rights groups filed with judges at a special war crimes unit in France's palace of justice a complaint regarding the Syrian government's use of chemical weapons. The complaints were accepted in Sweden, Germany and France and trigger a criminal investigation of Bashar al-Assad, his brother Maher, and other senior advisers and military officials. The complaint is based on evidence compiled by the Syrian Archive, and includes testimonies from survivors and defectors, an analysis of the Syrian military chain of command, and hundreds of items of documentary evidence, including photos and videos. In April 2021, lawyers representing victims of the attack filed a criminal complaint against members of the Syrian government, including Bashar al-Assad, with Swedish police, setting in motion a possible investigation into the role of Assad and other government officials. On 15 November 2023, French judges issued arrest warrants for Bashar and Maher al-Assad, as well as two unidentified Syrian government officials, for their involvement in the attack.
