Twenty-six PKK terrorists have been killed, 213 terrorist suspects have been detained in counter-terror operations in the past week, Turkey's interior ministry said Monday.

According to a statement by the ministry, 14 PKK terrorists have surrendered to security forces, while three others have been captured.

Founded in 1978, the PKK has waged a decades-long bloody campaign against Turkey.

The PKK, which is listed as a terrorist organization by Turkey, the U.S., and the EU, resumed its armed campaign in July 2015 after a brief reconciliation period.

Since that time, the PKK has been responsible for the deaths of some 1,200 security personnel and civilians, including women and children, while more than 4,000 security personnel and over 2,000 civilians have been injured.
