A mass grave containing the remains of dozens of civilians and security personnel apparently executed by terrorists has been found in northern Iraq's Kirkuk province, its governor said on Friday.

Rakan Said al-Juburi told AFP it was the 14th such discovery in the area.

"Local residents and shepherds guided security forces to the mass grave which appears to contain the remains of more than 75 civilians and security personnel," he said.

The governor said the victims had been "savagely executed by terrorists who occupied Hawija", one of the last urban centers held by the Daesh terror group before its ouster last year by Iraqi security forces.

The corpses found near Ryadh village, 45 kilometers (28 miles) west of the city of Kirkuk, had been shot in the head with their hands bound behind their backs, he said.

Residents fear that many missing relatives and friends, especially members of the security forces, have probably suffered the same fate.

Security forces have discovered dozens of mass graves since they drove out Daesh in 2017 after three years of occupation of swathes of northern and western Iraq.
