The attack caused no casualties or damages, he added without providing further details on the exact location impacted by the attack.

Earlier this year in two separate incidents, the PKK fighters killed five Peshmerga soldiers in a rocket attack in Matina Mountain, and killed another by a sniper fire near Zakho.

According to the official, delaying the exhumation process would only put the mass graves at greater risks, if not by hostile parties, by natural incidents.

“The International Coalition for Operation Inherent Resolve continues to support our partners in the Kurdistan Region of Iraq and the Peshmerga Forces,” Marotto wrote on Twitter.

The attack did not lead to any casualties or material damage, according to informed security and diplomatic sources who spoke to media.
