At least 1 arrest in deadly consulate raid 13 (UPI) -- Libyan Prime Minister Mustafa Abushagur said one person has been arrested and several others are being pursued in the deadly attack on the U.S. Consulate. Abushagur said Thursday the suspect who is in custody, along with "three or four" others being sought, are Libyans, CNN reported. He said there are "suspicions that these people belong to some extremist group, but ... that is something we don't know." "This is not acceptable to the Libyan people; this is not acceptable to our values," Abushagur said of the attack Tuesday, in which U.S. Ambassador to Libya Christopher Stevens and three other U.S. diplomats were killed. We are taking this very, very seriously. 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 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. Protesters burned a U.S. flag and set fire to tires and two vehicles. Security officials fired into the air, The Wall Street Journal 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. 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. 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.
