Turkish Defense Minister Hulusi Akar on Tuesday received U.S. Special Envoy to Syria, James Jeffrey, in the capital Ankara.
In a closed-door meeting, Akar expressed Turkey's discomfort at the YPG/PKK presence in Syria and said that the terror group must leave the region.
He also conveyed Turkey’s intention to continue protecting its security and regional interests in accordance with international law, as well as the need to completely rid the region from the terrorist organization.
In its more than 30-year terror campaign against Turkey, the PKK -- listed as a terrorist organization by Turkey, the U.S. and the EU -- has been responsible for the deaths of some 40,000 people.
The request came as Turkish and U.S. forces are carrying out joint patrols in the northwestern Syrian city of Manbij as part of a roadmap to clear the area of the YPG.
Turkey has carried out two-cross border operations against the YPG in Syria.
In a move long sought by Turkey, the NATO allies agreed in June to implement a roadmap for the northern Syrian city of Manbij, where Ankara had threatened to push its ground offensive despite the U.S. troops stationed there.
