UN Makes $1.6 Billion Appeal for Sudan Nabeel Biajo WASHINGTON - United Nations officials in Sudan have sent out an urgent appeal for $1.6 billion to provide life-saving assistance to citizens, including hundreds of thousands of people affected by floods. Recent flooding caused by heavy rain has affected 17 of Sudan's 18 states. More than 20,000 houses were destroyed and another 20,000 were damaged by the floods, according to Saviano Abreu, spokesperson for the U.N. Office for the Coordination of Humanitarian Affairs in Khartoum. "Here in Sudan we have around 250,000 people affected by floods that started in mid-July but intensified by the end of the month. During the month of August is when we saw most of the rain, concentrated in a short period of time," Abreu told VOA's South Sudan in Focus. .
