Turkish fighter jets neutralized six PKK terrorists in an operation in northern Iraq, the country’s National Defense Ministry said on Tuesday.

The ministry said in a tweet that the terrorists were neutralized in the Qandil and Metina regions by the Turkish Armed Forces with support from the country’s spy agency, the National Intelligence Organization (MIT).

Turkish authorities often use the word “neutralized” to imply the terrorists in question surrendered or were killed or captured.

PKK terrorists often use northern Iraq to plan cross-border terrorist attacks in Turkey.
