Two senior commanders of the Iraqi Armed Forces were killed in an attack by a Turkish drone in northern Iraq, Kurdistan24 news site reported on Tuesday.

Two border guard battalion commanders and the driver of their vehicle were killed in the attack, it said, citing the Iraqi army.

The drone had targeted "Iraqi border guard commanders while they were in meetings with PKK fighters," Ihsan Chalabi, the mayor of Sidakan in the north of Arbil province, told AFP.

The PKK is an armed group at war in Turkey for Kurdish autonomy for over three decades. The group is designated as a terrorist organisation by Turkey, the United States and the European Union. 

Turkey intermittently carries out air strikes against suspected PKK positions in the Kurdistan region.

The incident marks the first time regular Iraqi forces have been killed since Turkey launched a cross-border ground and air operation in mid-June against PKK rebels in northern Iraq.

Baghdad in June twice summoned the Turkish ambassador to the Ministry of Foreign Affairs over Ankara's intervention into Iraqi territories.
