The brothers, ages 27 and 30, were known to police prior to the attacks, the news outlet reports. One brother, Brahim El Bakraoui, is suspected of blowing himself up at the airport. His brother, Khalid, is suspected of detonating a bomb on a subway train.
The third suicide bomber has been identified by the local media as Najim Laachraoui, a 24-year-old who was already wanted by police as a suspect in the November 2015 Paris attacks. He is suspected to have been a bombmaker.
Police are searching for a fourth suspect seen on surveillance video, who has not yet been named.
More than 30 people were killed and at least 200 others were injured in a series of blasts in the Belgian capital Tuesday morning. The first two bombings happened at the airport, with the third occurring about an hour later on a train in a metro station.
1. The Brothers Are Suspected of Blowing Themselves Up in Separate Bombings
The brothers are believed to have blown themselves up during the attack at the airport, which occurred at about 8 a.m., and then at the metro station RTBF reports.
The bombs detonated by the terrorists are thought to have been concealed in suitcases.
Surveillance footage from the airport shows two men, Brahim El Bakraoui and Najim Laachraoui walking in the airport while pushing luggage carts. They are dressed in all black, and each has a black glove only on his one hand. A third man, dressed in white, is suspected of being involved in the attack, but is believed to have survived.
Khalid El Bakraoui is believed to have detonated a bomb at the metro station an hour later.

4. The Third Man Seen With the Brothers Is Also a Suspect in the Paris Terror Attacks
Authorities are still searching for a third man seen on the surveillance video with the two suspects. He has been identified by Belgian media as Najim Laachraoui.
The 24-year-old man, who has also used the name Soufiane Kayal, was already wanted by authorities in connection with the Paris attacks. He is believed to be part of the same ISIS terror cell that carried out those attacks last November. One of the leaders of that group, Salah Abdeslam, was arrested last week in Brussels.
His DNA was found on explosives used in Paris, AFP reported.
He is thought to have survived the attack on Tuesday. Federal police released his photo and asked the public to contact them with information.
4. Police Found a Nail-Filled Bomb, Chemicals & an ISIS Flag in a Raid on an Apartment After the Bombings
The so-called Islamic State has claimed responsibility for the bombings.
In a statement issued through its media service, ISIS said:
Islamic State fighters carried out a series of bombings with explosive belts and devices on Tuesday, targeting an airport and a central metro station in the center of the Belgian capital Brussels, a country participating in the international coalition against the Islamic State.
Belgian federal prosecutors said investigators found an explosive device containing nails, “chemical products” and an ISIS flag during a raid after the bombings, the Associated Press reports.
Authorities were led to the apartment by a taxi driver who drove the three men to the airport, without knowing of their plan. The taxi driver contacted police after the bombing.
