Belgian Police have released new footage of the only surviving suspect believed to have been involved in the Brussels bombing.
Two suicide bombers blew themselves up at an airport in Brussels while a third detonated an explosive at a metro station.
An unidentified third man seen standing next to the two suicide bombers at the airport is on the run. Belgian police have shown footage of him two hours after the bomb blast as they ask anyone with information about his whereabouts to come forward.
