Egypt's public prosecutor on Tuesday ordered that seven U.S.-based Egyptian Copts be tried over their role in an anti-Islam film that sparked violent clashes around the world, his office said.

The seven -- Adel Riad, Morris Sadek, Nabil Bissada, Esmat Zaklama, Elia Bassily, Ihab Yaacoub and Jack Atallah -- were accused of "insulting the Islamic religion, insulting the Prophet (Mohammed) and inciting sectarian strife."

Mitt Romney's White House campaign was rocked Monday by a secretly filmed video in which he said nearly half of Americans back President Barack Obama because they are government-dependent "victims" who pay no taxes.

Obama's team quickly seized on the film of Romney addressing rich donors, released by the liberal Mother Jones magazine, as proof the multi-millionaire candidate had written off half the nation and was not fit to be president.

Israeli Prime Minister Benjamin Netanyahu made a fresh push to turn the screws on Iran's nuclear program, saying the Islamic Republic's leaders are guided by "unbelievable fanaticism."

U.S. President Barack Obama urged Americans Saturday not to be disheartened by images of anti-American violence in the Islamic world, expressing confidence that the ideals of freedom America stands for will ultimately prevail.

President Barack Obama has vowed to "stand fast" against spreading anti-U.S. violence raging in the Arab world, as he mourned four Americans slain in Libya after their remains were flown home.

Egypt's Islamist President Mohammed Morsi Thursday slammed "attacks" on the Muslim prophet Mohammed in a film on Islam that sparked an outcry in Egypt, while also stressing that he condemned violence.

U.S. President Barack Obama called the leaders of Egypt and Libya to discuss security cooperation following the violence in Cairo and Benghazi, the White House said Thursday.
