A jury has found a French-born Isis fighter guilty of murdering four people at the Brussels Jewish museum five years ago.

Mehdi Nemmouche, 33, used both a Kalashnikov rifle and a handgun in the 84-second shooting spree captured on security cameras in May 2014.

Israeli tourists Miriam and Emmanuel Riva were shot in the head during the attack, while 26-year-old Belgian museum employee Alexandre Strens and 66-year-old French volunteer Dominique Sabrier also died.

The jury also found the gunman’s accomplice Nacer Bendrer guilty of murder.

Their seven-week trial heard Bendrer provided Nemmouche with his weapons.

Nemmouche sat impassively in court while Bendrer bowed his head as their verdicts were read out on Thursday evening.

The gunman faces up to 30 years in prison when he is sentenced on Monday.

The trial was striking for the arguments tabled by the defence lawyers, who attempted to suggest Nemmouche had been framed in an elaborate conspiracy organised by foreign intelligence agencies.

Israel’s agency Mossad, as well as those of Lebanon and Iran were mentioned, but the lawyers provided no evidence to support their claim.

Nemmouche was captured in France a week after the attack. The weapons he used were still in his possession.

He is also alleged to be one of the Isis militants who kept four French journalists hostage in Syria early in April 2014.

Nemmouche faces separate charges in France related to that incident.
