Turkey may shut off Incirlik base to US - media

Turkey is considering denying American access to the Incirlik Air Base, if the Kurdistan Workers' Party (PKK) Syrian affiliate Democratic Union Party and the People's Protection Units (YPG), participate in the Raqqa operation against ISIS, Yeni Safak reported with reference to the source.

The source added that it is possible that Ankara could close its airspace to American jets.

The Turkish government, which has repeatedly expressed its objection against the YPG's participation, during the ongoing talks with the Washington officials suggested that the Raqqa operation be conducted with the participation of the Free Syrian Army (FSA) along with local Arab and Kurdish elements.

The Incirlik Air Base in southern Turkey is a key base for the counter-ISIS coalition campaign in Syria.
