Franco-Algerian jihadist Mehdi Nemmouche, the man accused of shooting four people in the Jewish Museum in Brussels in May, is to be extradited from France to Belgium, according to a ruling by the French Supreme Court.
The 29-year-old man must now be brought to Belgium within 10 days, where officials will proceed with the criminal case.
In a terrorist attack on the Jewish Museum in Brussels on May 24, Nemmouche is alleged to have shot and killed four people: a couple of Israeli tourists, a French woman and a Belgian museum employee.
He was arrested a few days later during a customs inspection in the French port city of Marseille. Authorities said he was in possession of firearms, large quantity of ammunition and a video claiming responsibility for the attack that shocked Europe's Jewish community.
One of the weapons was wrapped up in a white sheet scrawled with the name of the Islamic State of Iraq and the Levant (Isis).
The Islamist group, known as one of the most violent among those active in Syria, has recently taken over large swathes of Iraq.
A court in Versailles, near Paris, ruled that Nemmouche should be handed over to Belgian authorities investigating the museum attack. Nemmouche had first opposed extradition, wary of being turned over to Israeli authorities.
Nemmoucbe left France for Syria as a jihadist in 2012, after serving time in jail over a series of crime, including an attempted robbery.
French authorities said he became radicalised while behind bars.
Hi return to Europe was notified to France by the German authorities but little attempt was reportedly made to keep track of him.
