Scores have been hurt after battles between police and hundreds of Muslims in Bangladesh's capital Dhaka. They were protesting against a film produced in the US that disparages the Prophet Mohammed.
Police in the city fired tear gas and used batons to disperse the stone-throwing demonstrators, who were from around a dozen Islamic groups.
Police said the clash erupted on Saturday morning when they tried to stop the protest.
Witnesses said the protesters burned several vehicles, including a police van, during the battles.
The protesters announced a nationwide general strike on Sunday to protest against the police action.
A Pakistani minister offered $100,000 (£61,600) on Saturday for the death of an online filmmaker.
US Embassies across the Muslim world have come under attack and a US school in Tunisia set on fire in protests against the anti-Islam film.
Protests against the anti-Islam film continue to spread with the US embassy in Yemen stormed, while protests continue in Egypt and Iraq.
