In September 2020, Azerbaijani troops crossed the “Line of Contact” dividing Karabakh. Turkey intervened on the side of Azerbaijan. Armenia supports Artsakh. Azerbaijan uses laser guided drones supplied by Turkey and Israel to target Armenian troops, villages and civilians. Azerbaijani military offensives against civilians are war crimes under the Geneva Conventions.
The establishment of the Azerbaijan Democratic Republic in 1918 began with the systematic extermination of the Armenian populations living in Azerbaijan and the provinces of Nakhichevan and Nagorno-Karabakh. Often viewed as an extension of the 1915 deportation and genocide of Ottoman Armenians, Azerbaijani forces in Baku slaughtered at least 15,000 Armenian civilians in the ‘September Days.’ Azerbaijanis also slaughtered 1,000 Armenians in 1919-1920 in the Karabakh cities of Shusha and Khaibalikend. These historic genocidal massacres contribute to Armenian distrust of Azerbaijan today.
Genocide Watch considers Azerbaijan to be at Stage 9: Extermination and Stage 10: Denial.
