Anti-Terrorist Operation Zone ( uk, Зона проведення антитерористичної операції, translit=Zona provedennya antyterorystychnoyi operatsiyi), or ATO zone ( uk, Зона АТО, translit=Zona ATO), is a term used by the media, publicity, the government of
Ukraine, and the
OSCE and other foreign institutions to identify Ukrainian territory of the
Donetsk and
Luhansk regions (oblasts) under the control of Russian military forces and pro-Russian separatists. A significant part of ATO zone is considered
temporarily occupied territory of Ukraine.
History
On 20 February 2018,
Ukrainian President Petro Poroshenko changed the status of the ATO zone from an anti-terrorist operation to "taking measures to ensure national security and defense, and repulsing and deterring the armed aggression of the Russian Federation in Donetsk and Luhansk oblasts".
This allows the
Ukrainian military to take charge of the zones instead of the Ukrainian secret service
SBU. As such, the ATO was renamed to JFO zone (Joint Forces Operation ( uk, Операція об'єднаних сил, ООС, translit=Operatsiya ob'yednanykh syl).
Military administrative division
The official borders of the ATO zone were defined with a list of localities and their geographical coordinates, approved in November 2014 by Ukraine's parliament, the
Verkhovna Rada.
