Turkish warplanes conducted an anti-terror operation in northern Iraq late Tuesday, killing 3 PKK terrorists and destroying 3 weapons arsenals belonging to the group.

According to military sources, the terrorists in the Zap area near the Turkish-Iraqi border were planning attacks against Turkish outposts.

The aircrafts returned to their bases in safety, the sources added.

Listed as a terrorist organization by the U.S. and the EU, the PKK resumed its armed campaign against the Turkish state in July 2015, unilaterally violating the cease-fire.

Since then, over 600 security personnel, including troops, police officers and village guards, have died in PKK attacks and more than 7,000 terrorists have been killed during operations across Turkey and northern Iraq, according to the military.
