The intelligence operation in the region is ongoing, the agency reported.
Tensions between Ankara and the Kurds escalated in July 2015 when a ceasefire between Turkey and the PKK, listed as a terrorist organization in Turkey, the United States and the European Union, collapsed over a series of attacks allegedly committed by the PKK militants.
