Another PKK terror attack took place in Baglar district of Diyarbakir early on Thursday when PKK terrorists targeted a police department with rocket launchers.
The attack resulted in substantial damage of two nearby cars while no casualties were reported.
The terrorists also opened fire on a state building in Sirnak for twice over the last two days, making it unusable.
Meanwhile, Turkish Army announced on Wednesday in its official website that a total number of 13 PKK terrorists were neutralized in Sirnak and Diyarbakir provinces during the most recent operations.
Security forces also seized a great deal of ammunition and weapons in those regions.
PKK is recognised as a terrorist organisation by Turkey, NATO, the US, and EU.
Turkey has long been confronted with armed attacks in its southeastern regions by the PKK, which was founded in 1974. Armed clashes and acts of violence have continued on and off for more than 30 years, claiming more than 40,000 lives.
PKK terror attacks have killed more than 200 security officials and over 30 civilians in Turkey since the group’s umbrella organisation, KCK, unilaterally ended a two-and-a-half-year-long ceasefire with the government on July 11.
