Belgian police are a hunting for a “third man” filmed with two suicide bombers at Brussels Airport, in the wake of Tuesday’s attacks in the capital.
There are also reports that there could have been a second bomber in the Maelbeek metro station attack, close to the European Commission headquarters.
The so-called Islamic State militant group has claimed responsibility for the blasts, which killed more than 30 people and left hundreds more wounded.
So what do we do know so far about the suicide bombers, the suspects and the overall investigation?
