They were killed at 3:00 p.m. local time (1200 GMT) when a Turkish drone attacked their vehicle on a road in the Chalmir area of Sinjar Mountain, some 120 km west of Nineveh's provincial capital Mosul, Xinhua reported citing Iraqi Kurdistan's counter-terrorism service’s statement.

The Turkish forces frequently carry out ground operations, airstrikes, and artillery bombardments in northern Iraq against the PKK, especially in the Qandil Mountains, the main base of the group.

The PKK is listed as a terrorist organization by Turkey, the United States, and the European Union.
