Turkey has destroyed 14 Kurdistan Workers’ Party (PKK) targets in northern Iraq's Qandil Mountains. The region is considered to be the headquarters of the PKK, which is designated as a terrorist organization by Ankara. Some 20 Turkish jets were involved in the attack on Monday. Speaking at a rally in the central Turkish city of Nigde, President Recep Tayyip Erdogan threatened to “drain the biggest of the swamps” in reference to the region, which he said was a “source of terrorism” affecting Turkey, according to Daily Sabah.
