suspect Salah Abdeslam has been wounded and arrested in a dramatic raid in Brussels after four months on the run.
Another man arrested, Monir Ahmed Alaaj, was also on a wanted list, Belgian prosecutors said.
Three members of a family accused of harbouring Abdeslam have also been detained.
French President Francois Hollande said he expected Abdeslam to be extradited to France "as rapidly as possible".
