A Belgian man shot in the attack at the Jewish Museum in Brussels died on Friday, bringing the death toll to four.
Federal prosecutors said the 24-year-old museum worker, who had been in a critical state since the May 24 shooting, died early on Friday afternoon.
An Israeli couple and a French woman were also killed when a gunman opened fire with a Kalashnikov
French national Mehdi Nemmouche
, arrested in the southern city of Marseille
on May 30, is suspected of having carried out the attack.
French prosecutors said he was carrying a Kalashnikov
, another gun and ammunition similar to that used in the shooting and that he was a repeat-offender who had spent most of 2013 fighting in Syria
with Islamist rebels.
Nemmouche, 29, refused to be extradited from France
during a court hearing on Wednesday. His refusal is likely only to delay rather than block his eventual transfer to Brussels
