Belgian authorities have charged two people with supplying fake documents to an Islamic State group militant who was involved in the November 2015 attacks in Paris that killed 130 people. Prosecutors said Thursday that the pair helped Khalid El Bakraoui, who was also responsible for a suicide bombing on the Brussels metro.

On Wednesday, Belgian police detained a man identified as Farid K. and a woman named Meryem E. B. According to the prosecutors, both of them assisted Bakraoui, who was involved in the planning for the Paris attacks. Prosecutors said that Meryem was released under strict conditions while Farid, who has been charged with participating in the activities of a terrorist organization, remains in custody.

"They are suspected of having provided Khalid El Bakraoui with the false documents later used in preparation for the Paris attacks," the prosecutors said in a statement.

After the Paris attacks on the evening of Nov. 13, 2015, Bakraoui blew himself up in the Brussels metro last March, as part of coordinated attacks that killed 32 people.

Last year, authorities in Belgium said that Bakraoui was known to U.S. authorities and also listed in American terrorism databases. He was also reportedly wanted on an international arrest warrant for terrorism in December and had rented an apartment used by the cell linked to the Paris attacks, which were claimed by ISIS.

Bakraoui was also known to Belgian authorities as he was arrested for having Kalashnikovs in his possession in 2011.

Last year, Salah Abdeslam, the man suspected of playing a major role in Paris attacks, was arrested and later extradited to France from Belgium. Abdeslam is suspected of helping transport three suicide bombers to Stade de France, where they blew themselves up, and is also believed to have purchased the detonators. Investigators earlier said that Abdeslam had planned to blow himself up during the Paris attacks but backed out at the last minute. Authorities reportedly said that Abdeslam was preparing attacks in Brussels before he was captured during a police raid in the Belgian capital.
