WASHINGTON, Sept 14 (Reuters) - Leaders in Egypt, Libya, Yemen and Tunisia, which have all seen attacks on U.S. diplomatic missions this week, must do all they can to restore calm and reject "the tyranny of a mob," U.S. Secretary of State Hillary Clinton said on Friday.
"This has been a difficult week," Clinton said as she spoke at a ceremony to mark the return of the remains of four Americans killed in an attack on the U.S. consulate in Benghazi, Libya on Tuesday.
"We've seen the heavy assault on our post in Benghazi that took the lives of those brave men. We've seen rage and violence directed at America embassies over an awful Internet video that we had nothing to do with, she added, standing in front of the flag-draped caskets of the four men.
"It is hard for the American people to make sense of that because it is senseless and it is totally unacceptable," she added, echoing comments earlier this week in which she said there was no justification for responding with violence to the video, which she has called "disgusting and reprehensible."
Clips of the video posted on the Internet portray the Prophet Mohammad as a womanizer, homosexual and child abuser.
For many Muslims, any depiction of the Prophet is blasphemous. Caricatures or other characterizations deemed insulting in the past have provoked protests and drawn condemnations from officials, preachers, ordinary Muslims and many Christians in the Middle East.
"The people of Egypt, Libya, Yemen and Tunisia did not trade the tyranny of a dictator for the tyranny of a mob," Clinton said at the ceremony attended by U.S. President Barack Obama.
"Reasonable people and responsible leaders in these countries need to do everything they can to restore security and hold accountable those behind these violent acts," she said.
