US-led coalition air strikes destroyed two key bridges used by Daesh jihadist group on Syria's side of the border with Iraq, a monitoring group said Friday.

The coalition on Thursday night "destroyed two bridges between the Syrian city of Albu Kamal and the Iraqi border," said Rami Abdel Rahman, director of the Syrian Observatory for Human Rights.

"These bridges are strategically important for Daesh's movements between Albu Kamal and Iraq," he said.
