UN: Civilians at Risk in 'Safe Zone'Along Turkish-Syrian Border Lisa Schlein GENEVA - Turkey Wednesday began a military operation in northern Syria against Kurdish fighters, days after the United States announced it was withdrawing troops from the area. The U.N. refugee agency earlier warned that a proposed safe zone along the Turkish-Syrian border would not protect civilians. The UNHCR says it is concerned by the prospect of a so-called safe zone along Turkey's border with a Kurdish-held enclave in northeastern Syria. The idea was originally proposed by U.S. President Donald Trump and has been embraced by his Turkish counterpart, Recep Tayyip Erdogan. .
