At least two PKK terrorists have been "neutralized" in an air operation in Turkey's southeastern Sirnak province, the governor's office said on Sunday.

Turkish authorities often use the word "neutralized" in their statements to imply the terrorists in question either surrendered or were killed or captured.

According to a statement, after the terrorists were spotted by a drone, an air operation was conducted near Mt. Gabar in Sirnak.

In its more than 30-year terror campaign against Turkey, the PKK -- listed as a terrorist organization by Turkey, the U.S. and the EU -- has been responsible for the deaths of nearly 40,000 people, including women and children.
