The civil war in Syria looks set to enter a new and even more dangerous phase, with government forces on the move to help Kurdish fighters under attack from Turkey. Turkish forces crossed into Syria last week. The Turkish government regards the Kurdish fighters as terrorists, and wants to occupy a buffer zone reaching 20 miles into Syria. The Kurds have now turned to Syria's President Assad for help. And today Syrian government forces entered several towns just south of the border - setting up a potentially dangerous confrontation with Turkey.
