ANKARA Turkish artillery has returned fire "in kind" into Syria, military sources said on Tuesday, marking its fourth straight day of shelling across the border.
Turkey on Monday warned Kurdish militia fighters in northern Syria they would face the "harshest reaction" if they tried to capture a town near the border, and accused Russia of a missile attack there that killed at least 14 civilians.
