Security forces in Yemen have shot live rounds in the air and fired tear gas at a crowd of around 2,000 protesters trying to march to the U.S. Embassy in the capital Sanaa.
Friday's protest comes a day after hundreds of protesters chanting "death to America" stormed the embassy compound and burned the American flag. The embassy said nobody was harmed.
Yemen's president, Abed Rabbo Mansour Hadi, quickly apologized to the United States and vowed to track down the culprits.
On Friday, protesters outnumbered police but security forces were able to keep the crowd about a block away from the embassy by afternoon.
The protests were sparked by an anti-Islam film produced in the United States that denigrates the Prophet Muhammad.
