Turkish warplanes destroyed at least 18 targets belonging to the Kurdistan Workers Party (PKK) in northern Iraq over the weekend, the state-run Anadolu news agency said on Sunday. The strikes, carried out on Saturday and Sunday, targeted the Hakurk, Zap, Metina, Gara and Avasin-Basyan regions of northern Iraq, Anadolu said, citing the Turkish military. Turkey regularly carries out airstrikes against PKK targets in the Qandil mountains. The PKK, considered a terrorist organisation by the United States, the European Union and Turkey, has waged a three-decade insurgency in Turkeys largely Kurdish southeast that has killed some 40,000 people. Turkey in January launched a separate military operation in northern Syrias Afrin region to sweep Syrian Kurdish YPG fighters from its southern border. Turkey considers the YPG an extension of the PKK. US support for the YPG in the fight against terrorist ISIS in Syria has strained ties between Ankara and Washington.
