PKK militants had opened fire on Turkish soldiers at a military outpost near the Iraqi border in the mountainous Cukurca area, triggering a clash between the two sides, the Hakkari governor's office said in a statement.
It said the Turkish military had sent a drone to the area which located the militants, before the F-16 jets carried out their strikes. One Turkish soldier was wounded in the clash and taken to hospital for treatment.
Eight killed in Turkish operation against Kurdish militants - governor
More than 40,000 people have been killed in the PKK's insurgency, launched against the Turkish state in 1984. Turkey, the United States and European Union have designated the PKK a terrorist group.
Since the collapse of a two-year ceasefire in July 2015 the mainly Kurdish southeast has suffered some of the worst violence since the conflict began.
