Frankly, one of the worst in some time.
First, the US Embassy in Egypt was attacked by a mob early on 9/11. Egyptian troops and police failed to stop the protestors from scaling the walls, ripping down and burning the US flag. The ostensible reason for the attack was an anti-Muslim film made by "Sam Bacille", an allegedly Israeli -American director. In fact, his identity is in doubt. There is considerable suspicion that the attack had been planned in advance and would have occurred with or without the film, in conjunction with the 11th anniversery of the 9/11 attacks
The US Embassy in Cairo responded with a statement seeming to decry the actions of the protestors but sympathizing with their complaints regarding the anti-Muslim film:
"the continuing efforts by misguided individuals to hurt the religious feelings of Muslims -- as we condemn efforts to offend believers of all religions."
