Senior Turkish and U.S. officials also discussed President Recep Tayyip Erdoğan's upcoming visit to Washington.
President Erdoğan is expected to visit Washington for a meeting with U.S. President Donald Trump on Nov. 13.
Erdoğan was scheduled to meet with Trump amid discussions on Turkey's Operation Peace Spring against the PKK-linked People's Protection Units (YPG) terrorists in northern Syria and pressure from the U.S. Congress to impose sanctions on Turkey.
Turkey launched Operation Peace Spring, the third in a series of cross-border anti-terror operations in northern Syria targeting terrorists affiliated with Daesh and the PKK's Syrian offshoot the People's Protection Units (YPG), on October 9 at 4 p.m.
The operation, conducted in line with the country's right to self-defense borne out of international law and U.N. Security Council resolutions, aims to establish a terror-free safe zone for Syrians return in the area east of the Euphrates River controlled by the U.S.-backed Syrian Democratic Forces (SDF), which is dominated by YPG terrorists.
