The Khojaly massacre (Azerbaijani: Xocalı soyqırımı, Armenian: Խոջալուի արյունահեղություն, romanized: Khojalui aryunaheghut’yun) was the mass killing of Azerbaijani civilians by Armenian forces and the 366th CIS regiment in the town of Khojaly on 26 February 1992. The event became the largest single massacre throughout the entire Nagorno-Karabakh conflict.
Khojaly was an Azerbaijani-populated town of some 6,300 people in the Nagorno-Karabakh Autonomous Oblast of Azerbaijan SSR, also housing the region's only airport in 1992. The town was subject to daily shelling and total blockade by Armenian forces during the First Nagorno-Karabakh War. Without supply of electricity, gas, or water, it was defended by the local forces consisting of about 160 lightly armed men.
