Gunmen ambushed a U.N. food agency aid convoy in Uganda's troubled northeast, killing one of the drivers and forcing the agency to temporarily suspend operations in the drought-stricken area, the World Food Program said Tuesday, according to AP. The World Food Program trucks were returning from delivering food to schools and other sites when they were attacked on Monday, the Rome-based agency said. The 41-year-old driver had joined the agency in 2001 and was from the Karamoja region where the attack occurred, WFP said. The attackers fled as escorting soldiers and the rest of the trucks in the convoy arrived at the ambush site, the agency said. In January, WFP began distributing food aid to some 500,000 people in Karamoja, an impoverished area that is suffering its third drought in six years.
