Nearly 260,000 people died during the famine that hit Somalia from 2010 to 2012, a study shows.Half of them were children under the age of five, says the report by the UN food agency and the US-funded Famine Early Warning Systems Network.The number of deaths was higher than the estimated 220,000 people who died during the 1992 famine.The crisis was caused by a severe drought, worsened by conflict between rival groups fighting for power.UN Food and Agriculture Organisation (FAO) senior economist Mark Smulders said the "true enormity of this human tragedy" had emerged for the first time from the study, done jointly with the Famine Early Warning Systems Network (Fews Net)."By nature, estimating mortality in emergencies is an imprecise science, but given the quantity and quality of data that were available, we are confident in the strength of the study," said Fews Net official Chris Hillbruner."It suggests that what occurred in Somalia was one of the worst famines in the last 25 years," he added.
