Belgian police have moved Europe's most wanted man from hospital to a high-security jail, where he will face questions about the Paris attacks and likely charges, a day after his arrest in a Brussels shoot-out.
Salah Abdeslam, 26, the first person suspected to have played an active part in attacks in Paris to have been taken alive, was held in a Brussels hospital after being shot in the leg during Friday's police raid near his parents' home.
He and a second man, identified as Monir Ahmed Alaaj, are expected to appear on Saturday before a magistrate, who should outline the charges they face and authorise their detention for five days.
Belgian and French prosecutors were also discussing on Saturday how to proceed with the investigation.
Security services will be seeking information from Abdeslam on Islamic State plans and structures, his contacts in Europe and Syria and support networks and finance. Over the past four months, France and Belgium have detained several people linked to the prime suspects but none they suspect of a major role.
French President Francois Hollande, who had been visiting Brussels for a European summit when Friday's drama unfolded, has said France would seek extradition for the Brussels-based Frenchman. Abdeslam was, Hollande said, definitely in Paris on the bloody night of Friday, November 13 when 130 people were killed.
Belgian Prime Minister Charles Michel summoned security and intelligence chiefs to an emergency sitting of Belgium's national security council, for the second time in four days.
Belgian Foreign Minister Didier Reynders told reporters that authorities had possibly foiled another attack.
"We are very happy to have taken such an important step in the investigation into to Paris attacks, but we're not at the end of the road," he said.
Friday's swoop came after fake passports and Abdeslam's fingerprints were found following a bloody raid on Tuesday in which Mohamed Belkaid, a 35-year-old Algerian not on security watch-lists, was shot dead and police officers wounded.
Abdeslam has been on the run for four months after returning from Paris to Brussels hours after the November 13 attacks.
His elder brother, a Brussels barkeeper who shared a chequered history of drugs and petty crime, blew himself up outside a Parisian cafe that night. Hollande said the younger man's role in the killings was unclear, but investigators were sure he helped plan the operation for the Syria-based group.
Since all the identified attackers were killed, Abdeslam offers France a chance to understand what happened.
Hollande said that many more people were involved in the attacks on a sports stadium, bars and cafes and a concert hall than first thought.
One of those may be Alaaj, who using the false name Amine Choukri had been briefly picked up by German police with Abdeslam in southern Germany in October 2015.
Near to the scene of Friday evening's raid in the Brussels borough of Molenbeek, Dominique, the owner of a newspaper and tobacco shop who said he knew Abdeslam, said the gunshots had been a shock for the whole community.
"Originally a very nice boy. How can it go that far? That's something else," he told Reuters television.
