Turkish Forces Push Into Syria, Clash With Kurdish Militia

On Sunday, after launching artillery and air strikes on a U.S.-backed Kurdish militia, Turkish ground forces advanced into northern Syria’s Afrin region. The Syrian-Kurdish YPG militia, supported by the United States but seen as a terrorist organization by Turkey, said it had repulsed the Turkish forces and their allies. Turkey is targeting the U.S.-backed fighters at a time when ties with ally Washington appear close to breaking point.
