All three men accused of involvement in a 2014 gun attack on a Jewish museum in Brussels must stand trial, a Belgian judge has ordered. 

Two Israeli tourists and two museum workers were killed when a gunman entered the building in the centre of the Belgian capital and opened fire with a Kalashnikov rifle.

Mehdi Nemmouche, the suspected gunman, has been in custody awaiting trial since he was arrested in the French coastal town of Marseille a week after the attack.

But a judge ruled on Thursday that two other men – Nacer Bendrer and Mounir Atallah – should face trial alongside him, public broadcaster RTBF reported.

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.
