CAIRO – Al-Qaida's most active branch in the Middle East called for more attacks on U.S. embassies Saturday to "set the fires blazing," seeking to co-opt outrage over an anti-Muslim film even as the wave of protests that swept 20 countries this week eased.

Senior Muslim religious authorities issued their strongest pleas yet against resorting to violence, trying to defuse Muslim anger over the film a day after new attacks on U.S. and Western embassies that left at least eight protesters dead.

The top cleric in U.S. ally Saudi Arabia denounced the film but said it can't really hurt Islam, a contrast to protesters' frequently heard cries that the movie amounts to a humiliating attack that requires retaliation. He urged Muslims not to be "dragged by anger" into violence. The head of the Sunni Muslim world's pre-eminent religious institution, Egypt's Al-Azhar, backed peaceful protests but said Muslims should counter the movie by reviving Islam's moderate ideas.
