Employees pack refined sugar at Kenana Sugar Company (KSC)'s main plant, 270 km (170 miles) south of Khartoum May 14, 2013. In a hangar-shaped factory hall in central Sudan a dozen workers rush to pack refined white sugar gushing from a funnel into paper bags to be loaded on three trucks parked outside. Next year, the management at KSC hopes the plant will be even busier as it plans to boost its output as the African country seeks to increase sugar exports.
