A worker loads boxes containing ballot papers into a waiting United Nations-African Union Mission in Darfur (UNAMID) helicopter at the airport in Al Fasher, northern Darfur April 8, 2010. The ballot papers will be transported to the voting center in the north Darfur town of Mellit. Sudan's looming elections have been hit by a series of boycotts by political parties complaining of widespread fraud, just days ahead of the presidential, legislative and gubernatorial polls.
