Terrorist in charge of PKK activities in Isparta arrested

Security forces arrested a PKK militant on Thursday in the western province of Isparta. The terrorist was reportedly in charge of the terrorist organization's activities in the province.

During a raid of a house in the Yedişehitler neighborhood, H.K. was captured with many documents related to the PKK. Following interrogation, he was charged with having links to terrorist organizations.

Beside the PKK's terror campaign in southeastern provinces, which is collapsing rapidly, the organization has attempted to spread their activities to western provinces.
