Protests are spreading in the Middle East over a U.S.-made film considered blasphemous to Islam. Earlier today, hundreds of Yemeni demonstrators stormed the U.S. embassy in Sana’a, smashing windows and burning cars before breaking through the compound’s main gate. Protests have also occurred in Egypt, Iraq, Iran, Tunisia and Bangladesh, as well as the occupied Gaza Strip. In Cairo, at least 13 demonstrators were injured today outside the U.S. embassy. Police reportedly used tear gas to disperse the protesters after they threw stones and Molotov cocktails. The protests follow Tuesday night’s storming of the U.S. consulate in the Libyan city of Benghazi that left U.S. Ambassador Christopher Stevens and three staffers dead. On Wednesday, President Obama vowed to bring to justice those responsible for the killings, which he said would not break the ties between the United States and Libya.

President Obama: “We reject all efforts to denigrate the religious beliefs of others. But there is absolutely no justification to this type of senseless violence. None. The world must stand together to unequivocally reject these brutal acts. Already, many Libyans have joined us in doing so, and this attack will not break the bonds between the United States and Libya.”

The Obama administration has dispatched an elite group of marines to the Libyan capital of Tripoli and sent U.S. warships toward the Libyan coast in a bid to ramp up security of U.S. personnel.
