Anti-U.S. protests continue as governments try to contain anger Demonstrators skirmished with security forces who had constructed a massive concrete wall to block off one access road to the embassy, witnesses said, and the crowd was slowly growing as residents streamed in from around the city. Meanwhile, the Egyptian government appealed for calm, with Egyptian President Mohamed Morsi appearing on state television to call for restraint. State television also repeatedly played a Thursday message from Secretary of State Hillary Rodham Clinton calling the made-in-America anti-Islam film "disgusting and reprehensible." But Morsi's Muslim Brotherhood organization was clearly struggling to address two constituencies on Friday: its conservative base, still furious at the U.S. government about the film, and an international audience warily contemplating future relations with Egypt. Even as the organization sent out an English-language tweet at 11:53 AM local time (4:53 a.m. in Washington) saying that it "cancels Friday's nationwide protests, announces it will be present only in #Tahrir, for symbolic protest against the movie," an Arabic-language statement at 12:12 p.m. from Muslim Brotherhood secretary general Mahmoud Hussein called for protests "in front of the mosques of the whole country ... to show the whole Egyptian people's anger." In Sanaa, Yemen, hundreds of protesters clashed with security forces near the U.S. Embassy. Security had been significantly increased after protesters on Thursday broke into the embassy compound, smashing windows and looting offices; guards, soldiers and police at first had done little to stop them. On Friday, a new roadblock had been set up to keep protesters farther away from the embassy, and two soldiers said they had been given orders to use live ammunition if the protests got too close to the compound. Protesters burned U.S. flags and chanted "Death to America, death to Israel," as they had the previous day. Security forces fired into the air, used tear gas and fired water cannons to keep the protesters away. The protests did not appear to have grown in size since Thursday. Several prominent conservative Muslim leaders have condemned the embassy break-in. In addition to the protests outside American facilities in several countries, an attack by militants on the U.S. Consulate in Benghazi, Libya on Tuesday resulted in the death of U.S. Ambassador J. Christopher Stevens and three other U.S. diplomatic personnel. Although analysts believe the attack was premeditated, and not directly linked to anger over the video mocking the prophet Muhammad, the bloodshed added to the urgency as the Obama administration tried to restore calm.
