New video shows alleged Brussels bomber's escape

Prosecutors in Belgium have released a new video that shows a third suspect in last month's Brussels airport attack allegedly leaving the scene after the bombing.

The suspect is believed to have been the only surviving participant in the attack on March 22. The two other suspects, identified as Najim Laachraoui and Ibrahim el-Bakraoui, are believed to have died in the airport bombing, which killed a total of 16 people.

In the video, the third suspect, who wears a distinctive hat and a light-colored jacket, is shown leaving the airport about 9:50 a.m. local time, just after the attack. Surveillance footage tracks the suspect as he moves on foot away from the airport, walking to the nearby town of Zaventem.

Later in the video he is shown without his jacket, which he may have discarded.

Belgian Federal Prosecutor Eric Van der Sypt told reporters on Thursday that authorities could not trace the suspect's movements after Zaventem.

Prosecutors have released the footage as part of a new appeal for information on the suspect. In particular, anyone who may have filmed or photographed the suspect or who may have come across the discarded jacket is asked to call 0800 30 300 if they are in Belgium and 003225544488 if they are calling from outside Belgium.

The airport bombing was part of a coordinated terror attack during which there was another explosion at Brussels's Maelbeek subway station, killing 16 more people. The Islamic State later claimed responsibility for the attack.
