French authorities have arrested seven people in connection with the Islamist attack against a Paris-based satirical magazine that shocked the world.
The French Prime Minister told Europe 1 radio that several people were held overnight following the shooting that killed 12 people and wounded 11 more at the offices of Charlie Hebdo magazine.
The interior ministry later specified that seven people had been arrested. They are all thought to be family and friends of the main suspects, brothers Said and Cherif Kouachi, who are still at large.
A third man who was named as a suspect in the aftermath of the shooting has turned himself in.
Mourad Hamyd, 18, surrendered at a police station in Charleville-Mézières northeaster France. His connection with the two brothers was not immediately clear.
Charleville-Mézières is the native town of the wife of one of the Kouachi brothers, with some reports suggesting Hamyd is the woman's brother.
