Widespread protests against U.S. over anti-Muslim film Last Updated 11:06 a.m. Angry demonstrations against an anti-Islam film shot in the United States spread to their widest extent yet around the Middle East and other Muslim countries Friday, as protesters smashed into the German Embassy in the Sudanese capital, and security forces in Egypt and Yemen fired tear gas and clashed with protesters to keep them away from U.S. embassies. An embassy worker in Khartoum told CBS News that there are a thousand protestors outside and the number is growing. Police are reportedly using tear gas against stone-throwing demonstrators. The protesters have so far not been able to get into the compound but they are trying, the worker said; police are holding them back. A U.S. State Department spokeswoman said there were reports of gunfire but that Sudanese police were working with U.S. security personnel. She said all U.S. personnel are accounted for. Confrontations between demonstrators and police were reported in Yemen and Tunisia, where smoke was seen rising from the U.S. Embassy compound from cars set afire. One protester was killed in the northern Lebanese city of Tripoli in clashes with security forces, after a crowd of protesters set fire to a KFC and an Arby's restaurant. Protesters hurled stones and glass at police in a furious melee that left 25 people wounded, 18 of them police. Media reports said as many as four people were killed during clashes in Sudan's capital, Khartoum. Protests were held in cities from Egypt to Pakistan after weekly Friday Muslim prayers, where many clerics in their mosques sermons denounced an obscure movie promoted on YouTube that denigrated the Prophet Muhammad. The wave of protests comes after attacks earlier this week on U.S. Embassies in Cairo and the Yemeni capital Sanaa and on a U.S. consulate in Libya, where the ambassador and three other Americans were killed. Additional protests were reported in Jalalabad, Afghanistan; Indonesia; Malaysia; Kashmir, India; Islamabad, Pakistan; Bangladesh; Lebanon; the West Bank and Gaza; Kuwait; Bahrain; Iran; and outside the U.S. Embassy in London, where around 120 demonstrators burned American and Israeli flags. Angry demonstrations over the anti-Islam video already had already occurred in Egypt and Yemen, and officials theorize that well-armed Libyan extremists hijacked a similar protest in Benghazi, where several Libyan security guards also were killed. After security forces earlier this week stood aside in the face of protesters, Yemen and Egypt made efforts Friday to contain them. In an apparent attempt to patch up strained ties with the United States, Egypt's Islamist president, Mohammed Morsi, went on state TV and urged Muslims to protect foreign diplomatic missions - his most direct public move to contain protests. The Muslim Brotherhood had called for more demonstrations today in Cairo, as did authorities in Iran and the Gaza strip. However, a statement on the Muslim Brotherhood's Twitter account said that it has called off the large protests today and will instead stage a "symbolic" demonstration against the movie in Tahrir Square. Sudanese policemen try to disperse protesters demonstrating against an amateur film mocking Islam, outside the German embassy in Khartoum, Sept. Police in Cairo have nonetheless prepared, reports correspondent Holly Williams from Cairo. They've erected a 10-foot high concrete barrier, blocking the way to the U.S. Embassy. But crowds of young men have clashed with Egyptian police near the embassy for more than 48 hours. The Egyptian Government knows that these protests are damaging, and they've come at a time when they're trying to rebuild the country after the Arab Spring, and attract foreign investment. However, the government draws its support from conservative Muslims - President Morsi himself belongs to the Muslim Brotherhood - and many of them are still furious about the film made in America that sparked these protests. And so, said Williams, authorities can't afford to crack down on them too hard. On Friday Morsi released a statement saying it's up to Muslims - as part of their Islamic duty - to protect embassies and foreign diplomats who are guests in the country. Still, protests broke out in several cities, fanned by clerics. In Sudan, a prominent sheik on state radio urged protesters to march on the German Embassy to protest alleged anti-Muslim graffiti on mosques in Berlin and then to the U.S. Embassy to protest the film. "America has long been an enemy to Islam and to Sudan," Sheik Mohammed Jizouly said. Soon after, several hundred Sudanese stormed into the German Embassy, burning a car parked behind its gates and setting fire to trash cans. Protesters danced and celebrated around the burning barrels as palls of black smoke billowed into the sky.
