"Salah Abdeslam… [has] been charged by the investigating judge with participation in terrorist murder and participation in the activities of a terrorist organization," the Belgian federal prosecutors office's statement said as cited by Reuters.
He was arrested on Friday during a raid by Belgian police in the Brussels district of Molenbeek, after a four-month manhunt.
A second man detained with Abdeslam, who had been identified as Monir Ahmed Alaaj alias Amine Choukri (both names appear on fake documents, according to investigators) has also been charged. A third man, who was also detained Friday, was charged with being part of a terrorist group and aiding criminals.
Earlier in the day, French President Francois Hollande said that Paris would ask for Abdeslam's quick extradition from Belgium to France as he is a French citizen.
