Original story:

The investigation into Tuesday's deadly terror attacks on Brussels is set to continue, as prime suspect Najim Laachraoui and at least one other unidentified suspect remain at large, Belgian federal Prosecutor Frédéric Van Leeuw said at a news conference Wednesday. The attack Tuesday, which left at least 34 dead and more than 200 wounded, rocked the de facto capital of the European Union as leaders throughout the continent looked to prevent future assaults.

Tuesday's attack began around 8 a.m. when two explosions rocked Zaventem, an international airport outside of Brussels. Around an hour later, a third bomb went off in a crowded subway car as it pulled into a station in central Brussels. The airport will remain closed through at least Thursday.

Police identified two suicide bombers as Khalid and Ibrahim El Bakraoui. Ibrahim El Bakraoui carried out the suicide bombing in the airport and Khalid El Kakraoui in the subway, the federal prosecutor confirmed Wednesday. A third suspect, Najim Laachraoui, is still at large.

At least two of the attackers are of Belgian nationality, and Belgian police carried out five raids across Brussels in search of the two suspects that remain on the run. The two dead terrorists had extensive criminal records, according to Van Leeuw.

The attacks came just days after the capture of Salah Abdeslam, believed to be the last living terrorist who directly participated in a series of massacres in Paris in November 2015 that left 130 dead and many more wounded. The prosecutor said he did not want to immediately tie the two attacks together. The terror organization known as the Islamic State Group claimed responsibility for both the Brussels and the Paris attacks.

"It is too early to establish a link with the Paris attacks," Van Leeuw told a news conference with Belgian Prime Minister Charles Michel on Tuesday.
