Three people, detained along with nine others in anti-terror operations related to the Paris attacks, have been released on Sunday.

According to police sources, the interrogation of the remaining nine suspects was extended for another 48 hours.

On Jan. 7, two gunmen attacked the Paris headquarters of satirical magazine Charlie Hebdo, leaving 12 people dead. The weekly is known for printing controversial material, including derogatory cartoons of Prophet Muhammad in 2006 and 2012.

Investigators said the suspects were not directly involved in the attacks but have been accused of assisting the militants logistically with guns and vehicles.

French media said investigators arrested the suspects based on DNA analysis and wiretapping.
