“Civilian and military areas in Garyan and Mizdah were hit on Monday night by the colonial and crusader aggressors,” Libyan television said in a written news flash.
Garyan lies about 100 kilometers south of the Libyan capital, Tripoli, while Mizdah is about 184 kilometers south of the capital.
Western coalition forces have been bombarding strategic cities across the war-hit country to push government forces back.
