A Turkish special operations police officer was killed and three others were injured in a terrorist attack in northern Syria, Turkey's Interior Ministry said on Sunday.
The casualties occurred when the Kurdish YPG militia attacked an armored vehicle with a guided missile in the Operation Euphrates Shield zone, the ministry said.
It added that one of the injured was in serious condition.
Turkey considers the Syrian Kurdish People's Protection Units, or YPG, terrorists for their links to a decades-long Kurdish insurgency inside Turkey that has killed tens of thousands. The same fighters were the United States' partners on the ground in fighting the Islamic State group. (With AA)
