The two suicide bombers carried out the Brussels airport attacks on Tuesday have been identified as brothers Khalid and Brahim El Bakraoui, local media reported on Wednesday.
The brothers were Brussels residents with criminal records, but have not been linked by local police to terrorism until now, the broadcaster RTBF quoted an unnamed source as saying.
The attacks on the Belgian capital's airport and a metro station, have killed 34 people and injured more than 180 others.
