Though no one was killed in the Cairo attack, four Americans, including Ambassador J. Christopher Stevens were killed in the assault in Libya. Stevens was a true friend of the people... he was fluent in Arabic and was known to go above and beyond in his diplomatic duties. He chose to go to Libya following the Arab Spring Revolutions in an effort to assist the people of Libya build a better life. This attack, condemned by many in Libya, may also have been a response to a controversial YouTube video posted by anti-Islamic, Christian fundamentalists from the United States.
The movie, called "The Innocence of Muslims" claims that the Prophet Muhammad had tricked people into following a false God and false religion and makes some extremely inflammatory claims against the most important figure in Islam.
It was reported overseas that the movie was endorsed by the White House, which is why the Consulate may have been attacked. It is now clear that this movie was in no way supported by any official from the United States... it was made by a private citizen exercising his freedom of speech.
