Azerbaijan shot down an Armenian Mil Mi-24 'Hind' combat helicopter in the disputed territory of Nagorno-Karabakh, reportedly killing at least two crew members and drawing a promise of retaliation from Armenia.
Armenia said that the helicopter belonged to the armed forces of the de facto Nagorno-Karabakh government and was on a training flight near the line of contact when it was shot down. "The enemy continues to carry out intensive fire from small arms of various calibres in the direction of the place of the incident," the statement said.
However, Azerbaijan's MoD said the helicopter belonged to Armenia and it had violated Azerbaijan's airspace and "attempted to attack Azerbaijani positions". It said that two crew members were killed and a third escaped the crash scene.
Armenian forces have controlled the disputed area of Nagorno-Karabakh since a war between them and Azerbaijan ended in 1994 with a ceasefire agreement brokered by Russia. However, Azerbaijan has been rearming heavily and regularly promises that it will take back the region. This year has seen a steady increase in ceasefire violations.
