Famine will break out in war-torn South Sudan within weeks unless massive funding for food aid is provided, aid agencies warned on Thursday. "If the conflict in South Sudan continues, and more aid can**t be delivered, then by August it is likely that some localised areas of South Sudan will slip into famine," warned Britain's Disasters Emergency Committee (DEC), a coalition of 13 major aid agencies. The United Nations has around 40 percent of the cash it needs, with a shortfall of over a billion dollars (760 million euros). "There is a very real risk of famine in some areas," DEC chief Saleh Saeed said, warning that "millions of people are facing an extreme food crisis."
