Fighting has broken out between Armenia and Azerbaijan, and the Armenian government has declared martial law and total military mobilization. There have reportedly been at least 16 military and several civilian casualties. The neighboring nations have been mired in a decades-long standoff over the contested Nagorno—Karabakh region. A ceasefire was brokered in 1994, but there have been flare-ups since. Sunday's escalation appears to be the worst since 2016. Both sides blame the other for instigating the fighting. The Armenian Defense Ministry said Azerbaijan launched an attack on civilian settlements Sunday morning, and in response Armenia shot down two helicopters and three drones and destroyed three tanks. Azerbaijan only acknowledged that one helicopter had been lost, and a defense ministry spokesperson said several villages in Nagorno-Karabkh "which were under enemy occuption for many years have been liberated."
