Standing in line is Peter Mamouk, a visibly emaciated elderly man with only one eye who is among the 21,000 people who have registered for food. When the fighting began, the farmer was separated from his wife and nine children, who are now in a camp for internally displaced people in Bentiu, a city which has seen some of the biggest battles in South Sudan. Peter fled for his life, leaving his home and possessions behind, and has been unable to grow any crops.
