The Bucha massacre occurred during the Russian occupation of the suburban Kyiv town between February and March 2022. After Russian forces withdrew on March 31, hundreds of civilian bodies were discovered, many showing signs of torture, bound hands, and close-range gunshot wounds.

Documented casualties: UN reports document at least 458 victims, including 9 children. As of October 31, 2022, OHCHR had documented 73 confirmed killings with an additional 105 under investigation.

Evidence collected: Satellite imagery from Maxar Technologies and OSINT analysis (Bellingcat) confirm bodies were present in the streets during Russian occupation. Intercepted phone calls document Russian operations called "zachistka" (cleansing) involving hunting, filtration, torture, and execution of civilians.

Attribution: The ICC opened war crimes investigations; New York Times investigations identify Russia's 234th Air Assault Regiment (76th Guards Air Assault Division) led by Lt. Col. Artyom Gorodilov as responsible for executions along Yablunska Street. EU and US attributed responsibility to Russian forces.

Timeline: February 27 - occupation begins; March 31 - Russian withdrawal; April 2 - first images released; April 3 - mass graves discovered; June 2022 - UN report.
