About 11 million people in Sudan will need food aid in 2010 because of conflict, drought and high food prices in the country, the Rome-based World Food Programme said. The number of the people needing food aid in South Sudan has also increased from about one million in 2009 to over 4.3 million this year. “One is the drought and the second factor is inter-tribal conflicts,” WFP Southern Sudan Coordinator Leo Van Der Veldon told reporters.
