"I am Charlie" - France in solidarity

The cover of the first edition of the French satirical weekly Charlie Hebdo since its staff were murderously attacked by Islamist gunmen last week shows a cartoon of the Prophet Mohammed crying and holding up a "Je suis Charlie" sign, under the words: "All is forgiven", AFP reports.

The front page was released to media ahead of the magazine's publication on Wednesday. Three million copies of the special "survivors' edition" are being printed and will be made available in 25 countries, translated into 16 languages because of international demand, the report said.

Worldwide sympathy and "Je Suis Charlie" solidarity rose up around Charlie Hebdo in the wake of the attack against it last Wednesday, in which 12 people were killed, including five of its top cartoonists.

But the magazine's fresh caricature of Mohammed could renew fury by some extremely devout Muslims who believe it is forbidden to depict their prophet in any way.

The two gunmen who attacked Charlie Hebdo's offices in Paris last Wednesday said as they left the scene that they had "avenged the Prophet Mohammed".

The staff first started receiving death threats in 2006 when they republished cartoons by a Danish newspaper, Jyllands-Posten, that had triggered violent riots in some Muslim countries.

The offices of the weekly were firebombed by suspected Islamists in 2011 when it published other cartoons making fun of Mohammed, causing no injuries.

The surviving employees of Charlie Hebdo have sworn to uphold its tradition of lampooning all religions, politicians, celebrities and news events. Islamic extremists have often been ridiculed in its pages through provocative and irreverent cartoons.

We will "cede nothing" to extremists seeking to silence them, the publication's lawyer, Richard Malka, told French radio on Monday, according to AFP.

"In each edition for the past 22 years there has not been one where there have not been caricatures of the pope, Jesus, priests, rabbis, imams or Mohammed," he said.

It would have been "surprising" if a Mohammed cartoon did not feature in the new issue, he said.
