Protests in Bangladesh over anti-Muslim film

Bangladeshi firefighters extinguish a smouldering motorcycle set on fire during a demonstration against the U.S.-made anti-Islam film mocking the Prophet Mohammad, in Dhaka, September 22, 2012.

(CBS/AP) DHAKA, Bangladesh - Officials and witnesses said scores of people have been injured in a clash in Bangladesh's capital between police and hundreds of Muslims who were protesting a film produced in the United States that denigrates the Prophet Muhammad.

Police say they fired tear gas and used batons on Saturday to disperse the stone-throwing protesters, who were from about a dozen Islamic groups.

Witnesses said the protesters burned several vehicles. Dozens of people were arrested.

The clash erupted when police attempted to block the demonstration. All protests near the city's main Baitul Mokarram mosque have been banned since late Friday to avoid unrest.

The protesters announced a nationwide general strike on Sunday to protest the police action.

The film, "Innocence of Muslims," which is blasphemous against the central figure of Islam, has sparked violent protests throughout the Muslim world that have killed dozens.

Thousands also took to the streets peacefully today in Nigeria.

Nineteen people died in Pakistan Friday in violent clashes in several cities, including Pashawar, Lahore and Karachi.

Pakistani officials had tried to contain the anger by declaring a national holiday and what they called a "Day of Love for the Prophet." It didn't work.

Police used traditional riot control measures and some unconventional ones - shutting down the cell phone network in places to try to foil the organization of the protests. Again, it didn't work.

The United States put out TV ads saying the government had nothing to do with the film that has caused such offense. But popular outrage - and the opportunity for some interest groups to manipulate it - left as many as 20 people dead.

Anticipated protests over another issue - the publishing in a satirical French magazine of cartoons deemed insulting to Muhammad - seems to have been limited, said CBS News correspondent Mark Philips. But French authorities say some of the schools and diplomatic missions they had closed will stay closed until the anger subsides . . . if it does.
