They were both arrested after a house raid in Brussels, the federal prosecutor's office said
A man and a woman have been charged on suspicion of providing fake documents to Paris attack planner Khalid El Bakraoui, officials say.
The suspects, named as Farid K and Meryem E.B, were both arrested after a house raid in Brussels, the federal prosecutor's office said.
Farid K, who was also charged with "participation to the activities of a terrorist group", has been remanded in custody.
Meanwhile, Meryem E.B was released "under strict conditions", the prosecutor said.
In a statement quoted by Reuters, prosecutors said "they are suspected of having provided Khalid El Bakraoui with the false documents later used in preparation for the Paris attacks."
After being involved in the planning of the Paris attacks in November 2015, Khalid El Bakraoui was one of the suicide bombers who targeted Brussels last March.
130 people were killed in the attacks in the French capital, while there were 32 victims of the attacks on the airport and a metro station in Brussels.
