Turmoil in the Arab world linked to a contentious video denigrating the Prophet Muhammad spread on Thursday, September 13 to Yemen, where hundreds of protesters stormed the United States Embassy, two days after assailants killed the American ambassador in Libya and crowds tried to overrun the embassy compound in Cairo, The New York Times reported. There were no immediate reports of American casualties. News reports also spoke of a separate protest in Tehran, where around 500 Iranians chanting “Death to America” tried to converge on the Swiss Embassy, which handles United States interests in the country. For a third straight day, protesters scuffled with police in Cairo, while in Iraq, a militant Shiite group once known for its violent attacks on Americans and other Westerners said the video “will put all American interests in danger.”
