Charlie Hebdo editor Stephane Charbonnier, who publishes under the pen name “Charb.”

Sipa news agency is reporting that French police have detained a man who is suspected of threatening to decapitate Stéphane Charbonnier, the editor-in-chief and cartoonist of the French satirical magazine Charlie Hebdo, after publishing naked caricactures of the Prophet Muhammad.

According to the report, the 43-year-old man is suspected of making the threat on an Internet forum, allegedly writing, “The essential thing is not to let him live in peace.”

Speaking about the cartoons, White House spokesman Jay Carney said the Obama administration believed the cartoons “will be deeply offensive to many and have the potential to be inflammatory.”

“We don’t question the right of something like this to be published,” he said. “We just question the judgment behind the decision to publish it.”

Charbonnier, who goes by the pen name “Charb,” defended the cartoons to the AP in part by telling reporters that Muhammad isn’t sacred to him.

“I don’t blame Muslims for not laughing at our drawings,” he said. “I live under French law. I don’t live under Quranic law.”

He also said he doesn’t regret publishing the cartoons, nor does he take responsibility for any violence that may ensue.

“We’ve had 1,000 issues and only three problems, all after front pages about radical Islam.”

Less than a year after their offices were firebombed for publishing a caricature of the prophet Muhammad, the French satirical magazine Charlie Hebdo has created a controversy in France for publishing cartoons depicting the prophet Muhammad naked in their latest issue.

Stephane Charbonnier, the editor of Charlie Hebdo, says the cartoons were an attempt to poke fun at the furor over the anti-Muslim film causing protests throughout the Arab world, and will “shock those who will want to be shocked.”

According to the French newspaper Le Monde, one of the cartoons inside the magazine, entitled “Muhammad: a star is born,” depicts a bearded figure crouching over to display his buttocks and genitals.

The front-page of the magazine features a cartoon of an Orthodox Jew pushing a Muslim man in a wheelchair, who is saying, “You mustn’t mock us!” under the headline “Untouchable 2,” a reference to a popular French film about a paralyzed rich man and his black assistant.

NBCNews.com has reported that France is temporarily closing its embassies and schools in 20 countries, fearing a violent backlash from protestors over the cartoons. French Foreign Minister Laurent Fabius said on France Info radio, “Is it relevant and intelligent in this environment to add fuel to the fire?”

Charlie Hebdo is available on news stands all over France and is a top publishing venue for many top, French gag cartoonists. “Hebdo” is French for “weekly” and “Charlie” is a reference to the iconic cartoon character, Charlie Brown.

Charlie Hebdo’s web site went down yesterday because of a hacker attack. Our own site at cagle.com went down for a time yesterday in response to an unusually sophisticated, denial of service attack.
