Gunfire in southern Beirut, ambulances heard BEIRUT (Reuters) - Gunmen armed with rifles and rocket-propelled grenades exchanged fire in southern districts of Lebanon's capital Beirut on Sunday night, security sources said, and residents could also hear the sound of ambulance sirens. There were no immediate reports of casualties from the clashes, which occurred after angry mourners tried to storm government offices in the centre of Beirut at the end of the funeral of an intelligence official assassinated on Friday.
