According to a military source who cannot be named due to restrictions on talking to media, a soldier was martyred in a terrorist attack in the southeastern Sirnak province where the PKK is active.
The soldier succumbed to his wounds in a state hospital. The terrorists reportedly escaped in a nearby forest.
Meanwhile, a terrorist was killed after clashes broke out in another area of Sirnak.
The PKK -- listed as a terrorist organization by Turkey, the U.S., and EU -- resumed its decades-old armed campaign in July last year.
Since then, PKK terrorist attacks martyred more than 700 security personnel and also claimed the lives of many civilians, including women and children, while nearly 8,000 PKK terrorists were killed in army operations.
Turkish President Recep Tayyip Erdogan on Sunday said the PKK had so far martyred 787 security personnel and 312 civilians and injured over 4,000 security forces and more than 2,000 civilians since July 20, 2015.
