In this Tuesday, May 1, 2012 photo, women walking along a street wear veils in accordance with the directives of Islamist group Ansar Dine, which is seeking to impose Shariah law on Mali's Tuareg-occupied north, in Timbuktu, Mali. While government soldiers were fighting each other this week for control of the capital Bamako, Islamist fighters were asserting control over the Texas-sized northern half of the country, setting up a possible showdown with Tuareg nationalist rebels, who are secular and who seized northern Mali in March alongside the Islamists.
