The air strikes were carried out between the hours of 11 p.m. and 2 a.m., the army said.
It also said it hit PKK locations in Sirnak province in Turkey`s southeast, including shelters and gun points.
The PKK`s 31-year-old conflict with the state erupted anew in July, with Turkey launching air strikes on militant camps in response to attacks on its security forces, ending a March 2013 ceasefire. Hundreds have been killed in the latest fighting.
Designated a terrorist group by Turkey, the United States and European Union, the PKK launched a separatist insurgency in 1984 in which more than 40,000 people have been killed. The state launched peace talks with its jailed leader in 2012.
