The Muslim Brotherhood has called for mass protests at mosques across Egypt on Friday to condemn the controversial anti-Islam film, Innocence of Muslims
Mahmoud Hussein, the Islamist group's secretary general, called for Egyptians of all political persuasions to join the protests.
Meanwhile, the Brotherhood has condemned the attack on the US consulate in Libya's Benghazi on Tuesday, which killed its ambassador to the country and three other staff.
“We strongly condemn the deadly attack on the US consulate in Benghazi and the tragic loss of life. We urge restraint as people peacefully protest and express their anger,” the Brotherhood said via Twitter.
The controversial film, which critics say defames Islam and the Prophet Mohammed, was produced by California-based American-Israeli Sam Bacile.
The film was initially thought to have been produced by members of the Coptic Diaspora. Maurice Sadek, a conservative Coptic Christian living in the US, and controversial Pastor Terry Jones, who is known for his burning of the Quran, are believed to have been promoting the film but were not involved in its production, according to reports in the Wall Street Journal.
Demonstrators took down the American flag from the walls of the US embassy in Cairo during a protest on Tuesday.
