Reuters photo and caption: "Protesters attempt to raise a Salafist flag with Arabic words that read, "There is no God but Allah and Mohammad is his prophet" after pulling down an American flag at the U.S. embassy in Cairo September 11, 2012. Egyptian protesters scaled the walls of the U.S. embassy in Cairo on Tuesday and some pulled down the American flag during a protest over what they said was a film being produced in the United States that was insulting to the Prophet Mohammad, witnesses said."

The US response is posted at the website of the US Embassy in Cairo:

The Embassy of the United States in Cairo condemns the continuing efforts by misguided individuals to hurt the religious feelings of Muslims – as we condemn efforts to offend believers of all religions. Today, the 11th anniversary of the September 11, 2001 terrorist attacks on the United States, Americans are honoring our patriots and those who serve our nation as the fitting response to the enemies of democracy. Respect for religious beliefs is a cornerstone of American democracy. We firmly reject the actions by those who abuse the universal right of free speech to hurt the religious beliefs of others.

Could Gov. Romney consider whether he has an opinion worth sharing with the American people about this nightmare?

UPDATE: Ray Ibrahim discusses the attack on the US Embassy in Cairo here, clarifying the nature of the flag:

Some clarifications for context: Islam's black flag with the shehada and sword inscription is not an al-Qaeda banner but rather Islam's most ancient banner, popularized by the Abbasid caliphs in the 800s. In other words, these protesters were not imitating al-Qaeda; rather they—and al-Qaeda—are imitating Islam's heritage, replete with jihad against the infidel. Same with the phrase "worshippers of the cross" [a phrase chanted by embassy protesters]—Islam's ancient appellation for the hated Christians.
