TURKEY has been accused of war crimes in northern Syria after its military attacked a convoy of vehicles rushing to a prison camp under attack by Isis militants, who were trying free fellow jihadists held there.

A Syrian Democratic Forces (SDF) vehicle was struck by a missile fired from a Turkish drone close to the village of Tiwena near Til Temir in Hasaka province on Friday. 

According to local sources, a leading Kurdish official was killed in the air strike, amid accusations that Turkey is effectively providing air cover for Isis.
