Belgium has extradited Paris attacks suspect, Salah Abdeslam, to face trial in France.
He was wounded and arrested in a dramatic raid in Brussels on March 18 after four months on the run, the BBC reports.
The 26-year-old French national was born in Brussels and lived there before the Paris attacks.
Some 130 people were killed and dozens wounded in co-ordinated attacks carried out by so-called Islamic State in Paris on November 13.
The federal prosecutor said Salah Abdeslam had been “surrendered to the French authorities this morning (in execution of the European Arrest Warrant issued by France on March 19, 2016)”.
It is not immediately clear where he has been taken, although it is known that he was transferred recently from prison in Bruges to the high-security jail at Beveren, near Antwerp.
Salah Abdeslam was indicted by Belgian authorities last week over a shoot-out in the Forest area of Brussels in which four police were wounded, three days before he was arrested.
