CHARLOTTE -- Protests are getting more violent outside the U.S. embassies in Egypt and Yemen. The violence follows Tuesday's attack on the U.S. Consulate in Libya in which four American diplomats were killed.
Protesters are angry over an anti-Islam film that they say mocks Islam's prophet Muhammad.
Hundreds of protesters are outside U.S. embassies in Cairo and Yemen to demonstrate against the film. Hundreds of protestors stormed the U.S. embassy compound Thursday in Yemen's capitol and burned the American flag.
After burning the flag, they replaced it with a black banner bearing Islam's declaration of faith: "there is no god but Allah." They also threw rocks and pushed through barbed wire fencing.
Meanwhile, U.S. embassies and consulates around the world are increasing security. President Barack Obama has called on the presidents of Libya and Egypt to ask them to work with the United States to ensure safety of diplomats.
The Pentagon also moved two warships to the coast of Libya. Both ships are equipped with tomahawk missiles that could be used if a strike was ordered.
Meanwhile, the Muslim community in North Carolina is speaking out against Wednesday's deadly attacks. They say the attackers are extremists and in no way represent their peaceful faith. They fear the incident will worsen negative stereotypes some people already have about Muslims.
"Just like you have people in the Muslim world reacting on their emotions and ignorance, on the other side you have people in the United States reacting with ignorance and on emotion, like we saw with the Sikh temple and a number of the crimes that have taken place in the Muslim community," said Jibril Hough from the Islamic Center of Charlotte.
Some Muslims are working with authorities to step up security around their facilities.
Meanwhile, U.S. officials are investigating whether the violence was planned to coincide with the anniversary of the Sept. 11 attacks.
