evidence: Bottom Line Up Front - Azerbaijani troops launched an attack to secure control of Nagorno-Karabakh, a territory inside Azerbaijan but inhabited and run mostly by ethnic Armenians, which has been fought over by Armenia and Azerbaijan since the Soviet Union collapsed. [...] On September 19, Azerbaijan began a military operation, including air strikes on military targets manned by ethnic Armenian separatists, to seize full control of the disputed Nagorno-Karabakh region. Since the fall of the Soviet Union, Azerbaijan and Armenia have feuded over Karabakh, which is inhabited by an estimated 120,000 ethnic Armenians who constitute 95% of the population and run a self-declared autonomous administration. The enclave is internationally recognized as part of Azerbaijan. The operation was intended to complete Baku’s goal of reversing its defeat in the first post-Soviet war over Karabakh in which Armenia forces, by 1994, seized control of not only the Karabakh territory itself but also most of its surrounding districts. Retrained and re-armed with weapons from Türkiye, including the sophisticated Bayraktar (TB-2) armed drones, Azerbaijan’s forces recaptured the districts surrounding Karabakh in 2020, and maintained those gains under a ceasefire brokered by Russia and monitored by a contingent of 2,000 Russian peacekeeping troops.
