Europe's most wanted held in Brussels for Paris attacks

Salah Abdeslam, 26, the first suspected active participant taken alive, was being held overnight in hospital with a slight leg wound, Belgian Prime Minister Charles Michel announced at a news conference alongside French President Francois Hollande.

"This is an important result in the battle for democracy," Michel said on March 18, adding that US President Barack Obama had called to congratulate the Belgian and French leaders.

A Belgian minister broke the news by tweeting, "We got him."

Prosecutors said a second wanted man, who used the false name of Amine Choukri, was also wounded and captured in the raid on the apartment in Abdeslam's home neighborhood of Molenbeek.

The operation, planned after fingerprints and passports were found in a bloody raid three days earlier, was staged in a rush after media leaked word that police had found Abdeslam's trail.

Hollande, who was visiting Brussels for a European summit, confirmed France would seek extradition for the Brussels-based Frenchman who, he said, was definitely in Paris on the bloody night of Nov. 13 when 130 people were killed.

Abdeslam's 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 major new chance to understand what happened.

It was now clear, Hollande said, that many more people had been involved in the Paris attacks on a sports stadium, bars and cafes and concert hall than was first thought. Security concerns remain, he added, "The threat level is very high."
