SANAA, Yemen - As violence outside U.S. embassies spread to new Arab capitals Thursday, two former U.S. ambassadors said the slow response Tuesday by Egyptian security officials in Cairo points to a security lapse that warrants investigation.
Tear gas was used on protesters outside the U.S. Embassy in Cairo on Thursday while anti-American demonstrators battled police outside the U.S. Embassy in Yemen's capital of Sanaa. The protesters were angered over an anti-Muslim film produced in the USA.
