One police officer was killed, four others were injured in counter terror operations against the PKK in Turkey's southeastern Diyarbakır province, reports said Friday.
According to reports, the police were carrying out air-supported raids against an apartment building used by a PKK cell in Diyarbakır's Kayapınar district.
The police officers were injured after the terrorists threw hand grenades from the apartment, reports said, adding that they were immediately taken to a nearby hospital but one of them succumbed to his wounds.
A PKK terrorist was also killed in the operation.
The PKK has avoided direct confrontation with the Turkish military since the early 2000s and usually carried out hit-and-run attacks, but the region's proximity to PKK camps and geographical conditions allow the terrorist group to mass its militants in a single location.
Founded in 1978, the PKK has waged a decades-long bloody campaign against Turkey.
The group, 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.
More than 12,000 PKK terrorists were also killed in the same period.
