South Sudan on Monday declared famine in some parts of the country, with more than three years of war leaving nearly five million hungry in what aid groups called a “man-made” tragedy. Isaiah Chol Aruai, chairman of South Sudan's National Bureau of Statistics, said some parts of the northern Greater Unity region “are classified in famine, or ... risk of famine”. Aid agencies said 100,000 people are affected by the famine, which threatens another one million people in the coming months. “A formal famine declaration means people have already started dying of hunger. The situation is the worst hunger catastrophe since fighting erupted more than three years ago”, said the statement by the World Food Programme (WFP), UN children's agency UNICEF and the Food and Agricultural Organisation (FAO).
