PARIS (AFP) - Some of the best-known cartoonists in France were among the 12 killed when gunmen stormed the office of satirical newspaper Charlie Hebdo in Paris on Wednesday, a judicial source said.

Editor-in-chief Stephane Charbonnier, known as Charb, and the cartoonists known as Cabu, Tignous and Wolinski were killed in the attack on the paper, which gained notoriety for repeatedly publishing caricatures of Prophet Muhammad.
