Three explosions went off in the Belgian capital the morning of March 22: two in the Brussels airport and another in the Maelbeek metro station. Islamic State has claimed responsibility for the attacks.
Two of the suspected bombers have been identified as Khalid and Brahim El Bakraoui. The brothers are believed to have died carrying out the attacks. A third suicide bomber was identified as Najim Laachraoui, who was previously linked to the Paris terror attacks in November 2015.
One suspect is still being sought by police.
The suspects were identified by a taxi driver who drove them to the airport. They had very heavy bags, and the heaviest one -- which turned out to contain the heaviest load of explosives -- had to be left behind because it didn't fit in the cab.
