Turkey’s government says its troops are prepared for an imminent assault on Kurdish fighters in northern Syria, after President Trump ordered U.S. troops to fall back from their positions on the Turkish-Syrian border. Kurdish fighters said they’re bracing for a “humanitarian catastrophe,” saying in a statement, “This attack will spill the blood of thousands of innocent civilians because our border areas are overcrowded.” This follows warnings that former Kurdish allies of the U.S. who feel betrayed by President Trump will abandon thousands of prisoners captured during the U.S.-backed war against ISIS over the past two years.
