[3] Due to the publication of Muhammad cartoons, Charb became subject to death threats from extremist Muslims.

His work included creating cartoons for the newspaper Les Nouvelles du Val-d'Oise and a magazine for the Utopia (cinéma) [fr] in Saint-Ouen-l'Aumône.

[10] In 2007 and 2008, he was a set cartoonist on the talk show T'empêches tout le monde de dormir on television channel M6.

[16] In September 2012, a man was arrested in La Rochelle, allegedly for having called for the beheading of Charb on a Jihadist website.

[22] Also on that list was Lars Vilks, as well as three Jyllands-Posten staff members: Kurt Westergaard (whose cartoons Charlie Hebdo had published), Carsten Juste, and Flemming Rose.

[28] One year after the massacre, it was translated to and published in English, with a foreword by Adam Gopnik, under the title Open Letter: On Blasphemy, Islamophobia, and the True Enemies of Free Expression.

[31] His funeral was held in Pontoise and included speeches by Luz, Patrick Pelloux, Jean-Luc Mélenchon, and Pierre Laurent.

The government ministers Christiane Taubira, Najat Vallaud-Belkacem, and Fleur Pellerin also attended the funeral.
