Another terrorist was captured in the Yuksekova district in the eastern province of Hakkari, the army also said.
The army has stepped up operations against the PKK -- both inside Turkey and in northern Iraq -- since Oct. 3 when terrorists carried out a deadly attack on a Turkish military outpost near the border, killing 17 soldiers.
The PKK is listed as a terrorist group by Ankara and much of the international community, including the EU and the United States.
