Belgian prosecutors have charged three men with terrorist offences, including a suspect who local media said appeared on security footage with two suicide bombers at Brussels airport shortly before they detonated their bombs.
Prosecutors named the third man as Faycal C while media identified him as Faycal Cheffou, and said he was the man wearing a hat and a light-colored jacket in last Tuesday's airport picture that showed three men pushing baggage trolleys bearing luggage.
Prosecutors said he had been charged with taking part in the activities of a terrorist group, and actual and attempted terrorist murder. His home had been searched though no weapons or explosives had been found.
Two other men, Aboubakar A. and Rabah N., were also charged with terrorist activities and membership of a terrorist group. Rabah N. was wanted in connection with a related raid in France this week that authorities say foiled an apparent attack plot.
A total of 31 people were killed, including three attackers, and scores wounded in the Brussels attacks which were claimed by Islamic State and, as well as the airport, included a bomb on a metro train in the city center.
The attacks in Brussels, home to the headquarters of NATO and the European Union, took place four months after Islamic State militants killed 130 people in Paris and sent shockwaves around Europe and across the world.
