Three people have been charged with supplying arms to jihadists who staged deadly attacks in 2015 on a Jewish supermarket in Paris and the Charlie Hebdo satirical weekly, a judicial source said.

Those charged this week include Samir L, believed to be linked to the sale of weapons to the supermarket attacker, as well as Miguel M and Abdelaziz A, who are thought to have been involved in trafficking arms between Belgium and France.

Seven people have already been charged over the assaults. The attackers had a wide array of weapons including guns that came from Slovakia. Investigators are trying to piece together how France-based jihadist Amedy Coulibaly obtained the weapons used in the January 9, 2015 attack on the supermarket.
