Brussels attacks: Who was behind the bombings?

Brussels was targeted in a series of deadly terrorist attacks on the morning of Tuesday 22 March that left at least 34 people dead and as many as 200 others injured.

Coming just days after the arrest of Paris attack suspect Salah Abdeslam in a suburb of Brussels, it appears that at least one of those behind the Belgian attack on the city's airport and metro system has been linked to the French massacre.

Here's what we know about the terrorists.

  • Najim Laachraoui

The third airport bomber has not yet been identified

Najim Laachraoui, a 25-year-old terror suspect, sought in connection with both the Paris terror attacks, is one of two attackers who blew himself up at Brussels Airport.

Wearing one black glove, believed to have hidden a detonator, he is pictured pushing luggage containing explosives through the airport.

Prosecutors found his DNA in houses used by Paris attackers last year and he is also believed to have traveled to Hungary in September with the Paris attacks prime suspect Salah Abdeslam.

Initial reports suggested the "man in white" on the right of the airport CCTV image was Laachraoui, but police sources later told AFP that he was in fact the bomber pictured on the lefthand of the picture, who died.

  • Khalid and Ibrahim El-Bakraoui

El-Bakraoui brothers Khalid and Ibrahim both carried out separate attacks - Ibrahim El-Bakraoui at the airport and Khalid El-Bakraoui at the metro station.

Ibrahim El-Bakraoui, pictured in the centre of the airport CCTV image, blew himself up when he detonated a bomb hidden inside a piece of luggage that he pushed on a trolley.

At least 14 people died in the airport attacks as a result of El-Bakraoui and Laachraoui's bombs.

Khalid El-Bakraoui set his device off at the city's Maelbeek Metro Station, killing 20 people.

Both brothers are said to have been known to police before the Brussels attacks and Turkey said on Wednesday that it had warned Belgium of Ibrahim El-Bakraoui's terror links after deporting him to the Netherlands.

According to reports, Khalid rented a flat in the Belgian capital, under a false name, which was involved in a raid last week and where an Islamic State flag, an assault rifle, detonators and a fingerprint of the Paris attacks prime suspect were found.

A third man, caught on CCTV at the airport with Ibrahim El-Bakraoui and Najim Laachraoui shortly before the attack, is known as the "man in white" and has still not been identified.

It is believed the failed suicide bomber fled after his bomb failed to detonate. He is still at large.
