More than 100 demonstrators have gathered outside the US Embassy in London for what they say is a peaceful protest against the American-made film mocking the Prophet Mohammed.
Messages on posters read: "America the Enemy of Islam and Muslims," "democracy and freedom on death row" and "Islam is coming."
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.
