Belgian prosecutors have launched a fresh appeal for help in finding a suspected third attacker in last month's bombings at Brussels airport.
At a press conference on Thursday, they have released new video footage and pictures of the so-called "man in the hat", and called for information about him. Prosecutors presented a video showing the man's escape route from the devastated departure hall back into central Brussels, where all traces of him were reportedly lost.
32 people were killed in coordinated terror attacks in the Belgium capital on March 22nd.
