Brussels has been on the highest level of terror alert since November's Paris attacks and has seen several operations in recent weeks linked to the hunt for Salah Abdeslam, who was caught on Friday.
The identities of some of the victims of Tuesday’s bomb attacks in Brussels have come to light, with a Peruvian woman, Adelma Tapia Ruiz, the first to be publicly confirmed dead.
A British man, David Dixon, is among the people known to be missing from the Belgian capital one day after the blasts at Zaventem airport and Maelbeek metro station killed more than 30 and injured an estimated 230 people.
A Moroccan woman has also been formally identified as a victim of the metro station attack by Moroccan diplomatic sources, according to Belgian media.
