On 10 January 2015, following the "Charlie Hebdo" shooting, the Porte de Vincennes siege of a kosher supermarket, and the 1,500,000-strong "march against hatred" in Paris, Dieudonné wrote on Facebook "As far as I am concerned, I feel I am Charlie Coulibaly." In this way he mixed the popular slogan "Je suis Charlie", used to support the journalists killed at the "Charlie Hebdo" magazine, with a reference to Amedy Coulibaly who was responsible for the hostage-taking at the kosher supermarket which included the killing of four Jews.
