Germany presses Turkey to show restraint in Syria

German Chancellor Angela Merkel has pressed Turkish President Recep Tayyip Erdogan to respond with restraint to the planned withdrawal of U.S. forces from Syria

Merkel's office said the leaders spoke by phone on Sunday and both stressed the importance of the U.N.-led political process in efforts to end the conflict in Syria. A statement from the chancellor's office said the Islamic State group has been pushed back but remains a "significant danger."

On Saturday, Russian and Turkish ministers agreed to maintain cooperation in northern Syria as U.S. forces prepare to withdraw and Turkey threatens to launch a military operation against U.S.-backed Kurdish forces.
