Tomorrow's issue of Charlie Hebdo will show Muhammad with a tear on his cheek, holding up a sign saying "Je suis Charlie" (I am Charlie) under the headline "Tout est pardonne" (all is forgiven).

This follows last Wednesday's attack by Islamist gunmen on the Charlie Hebdo office, in which 12 people were killed – including the magazine's editor, Stephane Charbonnier, and four of its well-known cartoonists.

Demand for the new edition has surged, with the magazine planning to print up to 3 million copies instead of its usual run of 60,000, according to Reuters.

The cover of the magazine acts as a call to forgive. Zineb El Rhazoui, who is one of the columnists to survive the attack on Charlie Hebdo and who worked on the latest issue, spoke to BBC Radio 4's Today programme about the new edition and her colleagues' attackers.

"We don't feel any hate to them," she said. "We know that the struggle is not with them as people, but the struggle is with an ideology.

"We feel at the Charlie Hebdo team that we need to forgive."

However, the latest cover of the magazine has already caused offence. The Guardian reports the reaction of Omer el-Hamdoon, the president of the Muslim Association of Britain, to the caricature:

"My reaction to the cartoon is disgust," el-Hamdoon says, "but tending more to annoyance as well, because I feel that what's happening here is not that different from what we witnessed back in 2005 with the Danish cartoons when media outlets went into a cycle of just publishing the cartoons just to show defiance. And what that caused is more offence."

The new issue will also include other cartoons featuring the prophet Muhammad as well as making fun of figures from other religions and politicians.
