Turkish Foreign Minister Mevlut Cavusoglu called on Saturday the United States to “immediately” withdraw its troops from the Kurdish-held city of Manbij in northern Syria. President Recep Tayyip Erdogan on Friday said Turkish forces would sweep Kurdish fighters from the Syrian border and could push all the way east to the frontier with Iraq, including Manbij - a move which risks a possible confrontation with US forces allied to the Kurds. Speaking to reporters, Cavusoglu also said Turkey wanted to see concrete steps by the United States to end its support for the Syrian Kurdish People’s Protection Units (YPG). Ankara said earlier it had been told by US National Security Adviser H.R. McMaster that Washington would not provide the YPG with weapons anymore. Ankara views the YPG as terrorists and as an extension of the outlawed Kurdistan Workers Party (PKK) and has been infuriated by US support, including arms and training, for the group.
