Militiaman from the Ansar Dine Islamic group detain men they say had contravened Islamic law by drinking tea with women in public at a roadside cafe in the northeastern Malian city of Gao, June 14, 2012. The leader of the Ansar Dine Islamic group in northern Mali has rejected any form of independence of the northern half of the country and has vowed to pursue plans to impose sharia law throughout the West African nation. Iyad Ag Ghali's stance could further deepen the rift between his group and the separatist Tuareg rebels of the National Movement for the Liberation of Azawad (MNLA) as both vie for the control of the desert region.
