Azerbaijani forces on Friday struck Stepanakert, the main city in Azerbaijan's breakaway Nagorny Karabakh region, wounding "many" people, an Armenian official said as fighting raged on for a sixth day. 

The Caucasus neighbors have been locked in a simmering conflict for decades over the region and new fighting that erupted on Sunday has been the heaviest in decades.

"There are many wounded among (Stepanakert's) civilian population, civilian infrastructure is damaged,"  defense ministry spokesman Artsrun Hovhannisyan said on Facebook without providing further details.

Armenia later shared images on Twitter of damage to civilian infrastructure caused by the Azerbaijani attack in Stepanakert, which showed a cracked road and a car with shattered window.

Following the alleged attack, Armenian defense ministry urged the Azerbaijani authorities to refrain from making provocative statements, and to not aggravate the situation further into receiving an actual missile retaliation.
