Brussels attacks: 'Two brothers' behind Belgium bombings

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.

Broadcaster RBTF quoted a police source as saying Brahim was a suicide bomber at Zaventem airport. Twin explosions there killed about 14 people.

It said Khalid was the suicide bomber at the Maelbeek metro station, where about 20 people died.

Belgium is observing three days of national mourning.

The nation held a minute's silence at midday (11:00 GMT) on Wednesday.

So-called Islamic State (IS) has said it was behind the attacks and warned that more would follow.

On Wednesday anti-terror police also carried out a raid in the Anderlecht area of the city, making at least one arrest.

However, earlier reports that the man held was wanted suspect Najim Laachraoui have been withdrawn.

First victim named

RTBF said the two brothers were known to police and had criminal records.

The broadcaster, quoting the police source, said that Khalid el-Bakraoui, 27, 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.

He was arrested in a raid in Brussels last Friday and is due to appear before a pre-trial court on Wednesday.
