Top Floor Flat

Guardian UK: The men in the top floor flat who sowed terror in Brussels - Neighbours in Schaerbeek did not notice anything odd until police came on Tuesday shouting at them to put their hands up

Soon afterwards, one of the men, heavily built Ibrahim el-Bakraoui, 29, who had been carrying explosive material in his bag, blew himself up at the airport terminal alongside a second as yet unidentified bomber who also died. The third man dressed in a light jacket, hat and glasses, whose luggage contained the biggest bomb, is thought to have left his bag and ran out of the terminal before the explosions. His bag was later blown up, causing no casualties, by police bomb disposal teams in a controlled explosion. He is still on the run.
