Update to this story.

Cue the rampaging mobs.

(AFP) — A French satirical magazine, whose offices were fire-bombed after it published cartoons lampooning the prophet Muhammad, published on Wednesday a comic book biography of Islam’s founder.

The editor of Charlie Hebdo weekly has insisted that the new book, titled “The Life of Muhammad”, was a properly researched and educational work prepared by a Franco-Tunisian sociologist.

“It is a biography authorized by Islam since it was edited by Muslims,” said Stephane Charbonnier, who was also the illustrator of the book whose front page shows the prophet leading a camel through the desert.

“I don’t think higher Muslim minds could find anything inappropriate,” he said last week.

Charbonnier said the idea for the comic book came to him in 2006 when a newspaper in Denmark published cartoons of Muhammad, later republished by Charlie Hebdo, drawing angry protests across the Muslim world.

“Before having a laugh about a character, it’s better to know him. As much as we know about the life of Jesus, we know nothing about Muhammad,” he said.
