Azerbaijan says it's struck enemy targets Nagorno Karabakh

Azerbaijan's defence ministry on Saturday released a video it says shows rocket and artillery strikes on alleged enemy positions, amidst a new escalation of their conflict with neighbouring Armenia over Nagorno-Karabakh.

The release of the footage, the date and location of which could not immediately be verified, comes as Azerbaijan in turn accused Armenia of striking its second-largest city with a ballistic missile that killed at least 13 civilians and wounded 50 others.

The Armenian Defense Ministry denied launching the strike, but the separatist authorities in Nagorno-Karabakh put out a statement listing alleged "legitimate" military facilities in the city of Ganja, although they stopped short of claiming responsibility for the attack.

While authorities in both Azerbaijan and Armenia have denied targeting civilians, residential areas have increasingly come under shelling amid the hostilities that have raged for three weeks despite Russia's attempt to broker a cease-fire.

Stepanakert, the capital of self-proclaimed Republic of Nagorno-Karabakh, came under intense shelling overnight, leaving three civilians wounded, according to separatist authorities.
