The head of Lebanon's Shi'ite militant group Hezbollah called for nationwide protests over a film about the Prophet Mohammad, saying that the US must be held accountable for creating strife between Muslims and Christians.
In a televised speech, Hezbollah Secretary-General Sayyed Hassan Nasrallah said: "We call for protests tomorrow in the southern suburbs (of Beirut) at 5 o'clock.
"Muslims and Christians must remain vigilant in order to refrain from sliding towards strife. Those responsible for the film, starting with the US, must be held accountable."
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.
