Karabakh war leaves civilians shell-shocked and bitter

The decades-old Nagorno-Karabakh conflict in the Caucasus is no longer frozen. Armenia and Azerbaijan are engaged in the heaviest clashes since the 1990s, despite Russian mediation efforts.

Azerbaijan says retaking the disputed territory is unfinished business - it is internationally recognised as part of Azerbaijan. The Armenians say Nagorno-Karabakh was historically Armenian for centuries.

BBC correspondents Orla Guerin and Steve Rosenberg found bitterness and patriotic fervour among civilians on both sides.
