Belgian authorities said Thursday they have put two more suspects in the Paris attacks in custody facing terrorism charges.

The federal prosecutor’s office said that at dawn on Sunday, a French national, identified only as Samir Z., was detained at Brussels national airport as he was seeking to fly to Morocco. The Frenchman had already tried twice to travel to Syria this year.

The suspect is said to be part of the entourage of Bilal Hadfi, one of the suicide bombers at the Stade de France on Nov. 13.

Prosecutors also said that a second man, identified as Pierre N., was arrested during a raid only hours after the detention at the airport early Sunday.

Both men hail from Molenbeek, a Brussels neighborhood linked to at least three other attackers in Paris.

Both men were charged with participating in the activities of a terrorist organization.

In all, Belgium now has eight suspects linked to the Paris attacks or a possible attack in Brussels behind bars.
