The main agency representing Muslims in France appealed for calm on Friday as a new print run of cartoons featuring a naked Prophet Mohammad hit newsstands, raising fears of protests on prayers day around the Islamic world.

The drawings in satirical weekly Charlie Hebdo risk stoking a furore over a film mocking the Prophet, which provoked the storming of U.S. and other Western embassies, the killing of the U.S. envoy to Libya and a suicide bombing in Afghanistan, reports Reuters.

French embassies, schools and cultural centres were shut in some 20 Muslim countries, on orders issued from Paris after the cartoons were first published.

In the French capital, police were on alert after protests planned by some Muslim groups were banned.

Mohammed Moussaoui, leader of the French Muslim Council (CFCM), described both the film and the cartoons as "acts of aggression" but appealed to French Muslims not to take to the streets for wildcat protests.

"I repeat the CFCM's call not to protest - any protest could be hijacked and counterproductive," Moussaoui told French radio station RFI.

Charlie Hebdo, an anti-establishment weekly whose Paris offices are under police protection, defied critics to rush out another run of the publication that caused outrage and sold out in minutes last Wednesday. It says the cartoons are designed simply to poke fun at the uproar over the film.
