All three Brussels Jewish museum shooting suspects must stand trial, judge rules

The two men were extradited to Belgium as suspected accomplices who helped plan the attack, but were later released under conditions.

Federal prosecutors had applied to dismiss the case against Mr Atallah, but their request was refused.

When he was arrested in Marseille Mr Nemmouche was carrying weapons and ammunition that appeared identical to those used in the museum attack, as well as an ISIS flag.

Israeli tourists Emanuel and Miriam Riva and museum volunteer Dominique Chabrier were killed during the attack on May 28, 2014.

Another museum worker at the reception desk, Alexandre Sterns, was critically wounded and died of his wounds a month later.
