The United Nations food relief agency is investigating the theft of food aid from lifesaving humanitarian operations in Ethiopia, according to a letter obtained by The Associated Press. The World Food Program’s Ethiopia director, Claude Jibidar, says in the letter that “WFP is very concerned about the large-scale sale of food in some markets” which “poses not only a reputational risk but also threatens our capacity to mobilize more resources for the needy people.” He adds that it “is therefore imperative that immediate actions be taken to curb … the misappropriation and diversion of humanitarian food” in the country. The letter is dated April 5 and addressed to humanitarian partners of WFP in Ethiopia, where drought and internal conflict have left 20 million of the country’s 120 million people reliant on aid.
