A man has been filmed climbing out of the window of a hijacked plane as negotiations continue with a man claiming to have a suicide vest. It was unclear how many people remained on EgyptAir flight 181 as it stood on the tarmac at an airport in Cyprus. A live stream appeared to show three other men disembarking the aircraft and being taken to safety by armed police. Egyptian officials previously said seven people remained on board with the hijacker - the capitain, co-pilot, an air steward, security officer and three passengers.
