Armenian–Azerbaijani border conflict

Azerbaijan shoots down Armenian military helicopter: Baku

Azerbaijani forces on Nov. 12 shot down an Armenian military helicopter, the defence ministry in Baku said, in a dramatic flare-up in the arch-foes' longstanding conflict over Nagorny Karabakh.
      
The downing marks the most serious military incident along the Karabakh frontier since the 1994 ceasefire that ended a bloody conflict over the disputed region.
