The widespread protests connected to an anti-Islam film privately produced in the United States has kept tensions high in the Muslim world, even as anti-American violence eased Saturday. With this relative break, the furor over the YouTube video has not gone away completely, nor has concern over safety and security at U.S. embassies. To that end, U.S. officials are proclaiming that Marine teams would be dispatched to protect U.S. diplomatic missions in Libya, Yemen, and Sudan, but it's no secret that U.S. troops haven't been welcomed in those parts of the world.

Yemen's parliament issued a statement early Sunday demanding U.S. Marines leave the Arab country immediately, calling the presence of any foreign forces — and U.S. troops in particular — "unacceptable." Even with the arrival of its troops, the U.S. government isn't taking chances in Yemen, and have closed its embassy in Sana'a through Saturday, September 29, because of the threat of "potential demonstrations," according to the State Department. Meanwhile, the Marines have returned in light of their pending trip to Sudan to further talks with the government there, according to a U.S. official.
