Protesters marched in Tehran Thursday and the U.S. Embassy in Kuwait was closed amid growing turmoil over a U.S.-made movie disparaging the Prophet Muhammad. Protests were also carried out in front of U.S. embassies in Tunisia, Morocco, Israel and Sudan, CNN reported. Hundreds of protesters stormed the U.S. Embassy in Sanaa, Yemen, Thursday -- two days after militants killed U.S. Ambassador to Libya Christopher Stevens and three other U.S. diplomats in Benghazi and protesters tried to storm the embassy compound in Cairo. Hundreds of protesters, mostly students, gathered at the Swiss embassy in Tehran, which serves as host to the U.S. Interests Section in Iran, Mehr News Agency reported. \"Based on article 7 of the U.N. Charter, any country which endangers the global security should account for its acts and we urge international organizations to seriously ask the U.S. to present explanations,\" the protesters said in a statement condemning the anti-Islam film, which was produced in the United States. They urged Muslims to condemn the movie and boycott YouTube, the website where a clip from the movie was posted. Some of the protesters in Tehran burned a U.S. flag and shouted \"Death to the U.S.\" and \"Death to Israel.\" The U.S. Embassy in Kuwait was being closed ahead of Friday\'s customary prayers, Press TV reported. White House press secretary Jay Carney told reporters Thursday the United States government \"had nothing to do with\" the movie at the center of the spreading protests. \"We reject its message and its contents,\" he said. \"We find it disgusting and reprehensible. America has a history of religious tolerance and respect for religious beliefs that goes back to our nation\'s founding. We are stronger because we are home to people of all religions, including millions of Muslims. \"We also believe there is no justification at all for responding to this movie with violence,\" Carney said. \"Islam respects the fundamental dignity of human beings and it violates that dignity to wage attacks on innocents.\" Witnesses in Sanaa Thursday said protesters broke through an outer perimeter and set fire to a building inside the compound before being forced to retreat, The New York Times reported. Protesters burned a U.S. flag and set fire to tires and two vehicles. Security officials fired into the air, the Journal said. Yemeni officials said a number of protesters were wounded and there were some arrests. President Abdu Rabbo Mansour Hadi of Yemen said in a statement he \"extends his sincere apologies to President Obama and to the people of the United States of America\" for the attack. The embassy, on its website, had warned of the potential of protests spreading to Yemen. \"The U.S. Embassy continues to recommend that U.S. citizens avoid large gatherings. Even demonstrations or events intended to be peaceful can turn confrontational and possibly escalate into violence. U.S. citizens in Yemen are urged to monitor local news reports and to plan their activities accordingly,\" the statement said. Earlier Thursday in Cairo, riot police fired warning shots and lobbed tear gas at hundreds of protesters outside the U.S. Embassy, CNN reported. Similar demonstrations against the movie, of which a 13-minute trailer was posted on YouTube, occurred outside the mission Tuesday and Wednesday. Six police officers sustained minor injuries in the latest protests, Egyptian Interior Ministry spokesman Alla Mahmoud said. Some protesters were treated on the scene for injuries. Witnesses said the demonstrators threw Molotov cocktails and rocks, CNN reported. A U.S. Navy destroyer took up a position off Libya\'s coast and another was en route, and about 50 elite Marines deployed to Tripoli were in place Thursday to provide security at the U.S. Embassy, officials said. Agents of the CIA, the FBI and other agencies were marshaled to identify and pursue the attackers who assaulted the U.S. Consulate in Benghazi Tuesday, killing the four Americans in an intense, four-hour firefight for control of the mission. U.S., Libyan and European officials have suggested militants used the demonstration as cover to stage a prearranged attack on the 11th anniversary of the Sept. 11 terror attacks on New York and Washington. President Barack Obama spoke with Libyan President Mohamed Magariaf Wednesday, thanking him for his condolences and expressing appreciation for the government\'s assistance in responding \"to this outrageous attack,\" a readout of the conversation provided by the White House indicated. Obama said the Libyan government must continue to workwith the United States to assure the security of U.S personnel in Libya. \"The president made it clear that we must work together to do whatever is necessary to identify the perpetrators of this attack and bring them to justice,\" the readout said. In a conversation with Egyptian President Mohammed Morsi Thursday, Obama \"underscored the importance of Egypt following through on its commitment to cooperate with the United States in securing U.S. diplomatic facilities and personnel,\" a readout indicated. \"The president said that he rejects efforts to denigrate Islam, but underscored that there is never any justification for violence against innocents and acts that endanger American personnel and facilities,\" the White House said. Stevens\' body was not located until dawn Wednesday, when he was found dead at a Benghazi hospital, U.S. and Libyan officials told The New York Times. It was the first time since 1979 a U.S. ambassador had been killed in a violent assault. Officials told several news organizations the attackers were organized, well trained and heavily armed, and they appeared to have some level of advance planning. \"Make no mistake, justice will be done,\" Obama said in a somber appearance in the White House Rose Garden Wednesday. Libyan leaders in Tripoli vowed to track down the attackers and stressed their unity with Washington, as Magariaf apologized and pledged new measures to ensure the security of foreign diplomats and companies. Residents of Tripoli and Benghazi staged demonstrations Wednesday night in support of the United States, condemning the attack and expressing sorrow at the embassy deaths.
