The attackers were said to have been spotted by aerial reconnaissance.
The incident occurred a day after PKK militants killed five Turkish soldiers and wounded eight more in the Hakkari province.
Tensions between Ankara and the Kurds escalated in July 2015 when a ceasefire between Turkey and the PKK collapsed over a series of terror attacks allegedly committed by the PKK members. Turkish authorities have imposed several round-the-clock curfews in Kurdish-populated towns in country's southeast, preventing civilians from fleeing the regions where the military operations are taking place.
The Kurds comprise ancient tribal groups, which are currently living in parts of Turkey, Iran, Iraq and Syria. In Turkey, Kurds represent the largest ethnic minority, and are striving to create their own independent state.
