Brussels: Two of the men who carried out attacks in Brussels on Tuesday have been named by Belgian media as the brothers Khalid and Brahim el-Bakraoui.
The RTBF broadcaster said the pair were known to police. It is believed at least one was among three suspects seen in a CCTV image at Zaventem airport.
Twin explosions at the airport and another at a metro station on Tuesday left about 34 dead and 250 wounded.
Belgium is observing three days of national mourning. So-called Islamic State (IS) has said it was behind the attacks and warned that more would follow.
A minute’s silence for the victims will be held at midday. RTBF said the brothers were known to police and had criminal records.
The broadcaster said that Khalid el-Bakraoui had used a false name to rent the flat in the Forest area of the Belgian capital where police killed a gunman in a shootout last week.
It was during that raid that police found a fingerprint of Salah Abdeslam, the main suspect in the Paris terror attacks of 13 November.
