Belgian police identified terrorists responsible for a terror attack at Brussels airport as Khalim and Ibrahim el Bakraui brothers, reports DW citing German broadcaster RTBF.

The El Bakraui brothers had no previous terrorist record and were mainly known to police as big-time gangsters. One of the brothers used a fake identity to rent an apartment at the Fore commune at 60 Dris Street , a site where a shootout occurred between terrorists and police during a police raid and where Salakh Abdesalam, a man believed to be responsible for the terror attacks in Paris, stayed in hiding.

Earlier on, police released a photo of a man suspected of masterminding terror attacks in Brussels.

Two explosions were reported to have occurred at Brussels’ Zaventem airport at 8 a.m. local time on March 22.

Two more explosions were reported at two subway stations, not far from a neighborhood where emigrants reside.

The Belgian government has officially recognized the attacks, which left 34 people killed and 200 injured, acts of terrorism.

The attacks might have been retaliation for a March 18 arrest of Salakh Abdesalam, a man suspected of masterminding terror attacks in Paris.

Some reports suggest ISIS has claimed responsibility for the terror attacks in Brussels.
