A plume of smoke rises on the air from inside Syria, as seen from the outskirts of the border town of Kilis

The Turkish border town of Kilis was struck by a missile fired from Syria on Sunday, a Reuters witness said, the fifth cross-border missile fired in the same day.

There were no immediate reports of casualties, as Turkish ground forces pushed into northern Syria's Afrin province after launching artillery and air strikes on a US-backed Kurdish militia it aims to sweep from its border.
