Nagorno-Karabakh Public TV company ArtsakhTV released on Sunday (October 4) footage of what is said to be aftermath of heavy shelling going on in the capital of the breakaway region.
Eighteen Nagorno-Karabakh civilians were killed by fire from Azeri forces and more than 90 were wounded in the past week, RIA Novosti news agency cited an official in the breakaway region as saying on Sunday.
The developments marked a sharp escalation of the war in the South Caucasus.
Armenia denied it had directed fire "of any kind" towards Azerbaijan. The leader of Nagorno-Karabakh said his forces had targeted a military airbase in Ganja but later stopped firing in order to avoid civilian casualties.
