The U.S. ambassador to Libya and three other members of the embassy staff were killed after the protesters threw rockets at the U.S. consulate in Benghazi on Tuesday. Riots have cropped up in Benghazi and in Cairo over an amateur U.S. film that is seen as being offensive to Islam. President Obama "strongly condemned the outrageous attack" while U.S. Secretary of State Hillary Clinton expressed "profound sadness." The ambassador, Christopher Stevens, was paying a short visit to Benghazi when the consulate came under attack. He reportedly died from smoke inhalation after rocket-propelled grenades were thrown at the building and it caught fire. An angry mob stormed the U.S. embassy in Cairo on Tuesday, pulling down the American flag and then attempting to burn it outside the embassy walls.
