The military also reported clashes in Turkey's Diyarbakir and Sirnak provinces, where one fighter was said to have been killed.
Continued operation
Rifles, ammunition, explosives and other materials were seized by Turkish soldiers.
Turkish warplanes have targeted positions belonging to the Kurdistan Workers' Party (PKK) in northern Iraq since mid-December.
Ankara says thousands of PKK rebels use a remote, mountainous part of northern Iraq as a base from which to launch attacks aimed at targets inside Turkey.
In February, the army conducted a week-long ground offensive against PKK hideouts in the region, where the group has long taken refuge.
