A Libyan military helicopter flies over a demonstration by Ansar al-Shariah Brigades and other Islamic militias, at Victory Square, in Benghazi, Libya, Sept. 21, 2012. The attack that killed the US ambassador and three other Americans has sparked a backlash among frustrated Libyans against the heavily armed gunmen, including Islamic extremists, who run rampant in their cities.
