A Belgian prosecutor has identified two of the attackers who targeted the Brussels airport and subway as brothers Ibrahim and Khalid El Bakraoui but says another unidentified attacker remains at large.
Federal Prosecutor Frederic Van Leeuw told reporters Wednesday that Ibrahim El Bakraoui, 29, and another as yet unidentified suicide bomber attacked the airport.
A third attacker also came to the airport with an explosive in a bag, but it exploded later and no one was hurt, the prosecutor said.
He said Khalid El Bakraoui, 27, blew himself up at the Maelbeek subway station. The attacks Tuesday killed at least 31 people and wounded 270, he said.
Belgian authorities say several people possibly linked to attacks are still at large.
