Two brothers have been tagged as the suspected suicide bombers who detonated explosives at the Brussels airport, a senior Belgian security source told CNN.
Khalid and Brahim El Bakraoui are suspected of having ties to the November terror attacks in Paris, the CNN report quoted the source as saying on Wednesday, March 23.
More than 30 people were killed and over 200 were injured when separate bombs exploded at the Maelbeek subway station and Brussels Airport on Tuesday, March 22.
The brothers were known to police for organized crime, but not for acts of terrorism, Belgian state broadcaster RTBF reported, according to CNN.
As officials try to learn more about the El Bakraoui brothers, investigators are scrambling to find a third suspect believed to be at large, the report said.
That man, shown in surveillance footage wearing a light-colored jacket and black hat, was seen pushing a luggage cart along with the other two suspects, the report said.
“The third man left a bomb in the airport, but it didn’t explode,” Belgian Interior Minister Jan Jambon said. “We are now looking for this guy.”
