Suspects linked to the jihadist attacks that struck the Paris region in January 2015 will stand trial from April to July next year, a legal source said on Friday.
A special Paris criminal court will hear the case against 14 people accused of helping the attackers who killed 17 people in a three-day series of attacks.
The victims included 12 people killed at the offices of the satirical magazine Charlie Hebdo by Cherif Kouachi and his brother Said on January 7, 2015.
Over the following two days the third gunman, Amedy Coulibaly, shot dead a young policewoman and killed four people at a Jewish supermarket.
All three gunmen were killed by police.
The suspects going on trial next year are accused of providing them with logistical support.
The three attackers had claimed allegiance to jihadist groups.
The source told AFP the trial would run from April 20 to July 3, 2020.
Since those killings, more than 250 people have died in a series of jihadist-linked attacks in France.
