Nagorno-Karabakh leader Arayik Harutyunyan said on Twitter that "mil objects in large cities of Azerbaijan are the target of the Defense Army of #Artsakh. Calling on Azerbaijani population to leave these cities to avoid inevitable loss." Artsakh is the Armenian name of Nagorno Karabakh.
But Harutyunyan later tweeted that firing had "stopped."
"Currently firing stopped upon my command to avoid loss among #civilians. Failing Azerbaijani military-political leadership to draw appropriate lessons, our commensurate response will pursue. Determined as never. #Azerbaijan can still stop its aggression," he wrote.
Long-simmering tensions between Armenia and Azerbaijan have flared up recently in the contested Nagorno-Karabakh region, with both sides accusing each other of attacking civilians amid reports of casualties.
