UN Official Slams Report on Somalia Food Diversion Lisa Bryant 25 March 2010 The United Nations aid chief in Somalia says a report alleging widespread corruption in food aid deliveries is unsubstantiated, and has caused donor countries to withhold funding. In a letter obtained by news agencies Thursday, the U.N.'s Mark Bowden said the allegations have generated bad publicity, and have affected humanitarian assistance to Somalia, where more than half the population is in need of aid. Bowden was referring to a report, widely publicized two weeks ago, in which U.N. investigators said up to half of the food aid intended for hungry Somalis is diverted to Islamic militants, corrupt contractors and local U.N. workers. The U.N. Monitoring Group on Somalia said in the report that food transporters, armed groups and other players often work together to sell food aid illegally and split the profits. In his letter, Bowden said the investigators' estimates of diversion are not based on facts but rather on "hearsay and commonly held perceptions." Bowden said U.N. agencies are doing their best to limit risks in a complex environment that has long been dominated by violent conflict. The World Food Program Executive Director Josette Sheeran reiterated Thursday that there is "zero evidence" for the report's claims. She welcomed any external investigation. Food supplies are often uncertain in Somalia after years of drought and unrest. The U.N. agency says it supplied food to 3.3 million Somalis during 2009. It recently suspended food deliveries in southern Somalia because of what it called threats and unacceptable demands from armed groups. Among its recommendations, the U.N. Monitoring Group on Somalia called for rebuilding the WFP's distribution network in Somalia. Some information for this report was provided by AP and Reuters. .
