The French satirical publication's offices in Paris were firebombed in 2011 after it published images of the Prophet Muhammad. Since it first appeared in 1970, the mag has gone after political and religious figures of all stripes. On Wednesday, at least 10 employees, including the editor, of Charlie Hebdo were killed, along with two police officers, in a terror attack, French officials said.
Charlie Hebdo editor Stephane Charbonnie, known as Charb, proudly flaunted his controversial magazine. He was reportedly killed in Wednesday's attack.
