Turkey demanded, during a meeting with armed opposition faction in Idlib, withdrawal from demilitarized zones, according to Sochi deal between Russian president Vladimir Putin and Turkey’s president Recep Tayyip Erdogan. Erdogan has announced that the withdrawal of radical groups had already started. German Chancellor Angela Merkel said Friday she and the leaders of Turkey, Russia, and France planned to hold a summit next month on the situation in war-ravaged Syria. “We are in favor of a four-way meeting with the presidents of Turkey, Russia and France and myself because the situation (in Syria) is still fragile,” Merkel told reporters after talks with Erdogan. “We aim to do this in the month of October,” she added. Turkish Foreign Minister Mevlut Cavusoglu is set to pay an official visit to France on Sept. 30 to hold discussions with his counterpart Jean-Yves Le Drian, said a Turkish Foreign Ministry statement. In this context, Cavusoglu called on Washington to stop the shipment of arms to the People’s Protection Units, or YPG, according to Washington Post. Washington has used 5,000 trucks and 2,000 cargo planes to deliver weapons to the YPG in recent years, he added. The political arm of a terrorist group seeking to peddle influence in Washington is a shocking state of affairs, and President Trump should block its activity.
