Targets included, according to Reuters, areas in Avasin, Basyan, Haftanin, Metina and Qandil. Turkey has often sent its air force to bomb PKK sanctuaries in those barren areas as part of its wider campaign to crackdown on the PKK in its own Kurdish-majority southeast.
Camps and ammunition depots were reportedly targeted in the strike.
The conflict between Ankara and the PKK flared up again after a shaky two-and-a-half-year ceasefire between the two collapsed in July 2015.
Since then Turkey has intensified its crackdown with blanket curfews on areas with PKK sympathizers across the southeast. Such as Cizre and the Sur district of Diyarbakir.
The PKK has had sanctuaries in the Kurdistan Region since the early 1980's and has established mountainous headquarters there.
Turkish officials have also said that a PKK bomb blast targeted two armored police vehicles near the Turkish frontier with Iraq on Friday. Two officers were injured.
