MOGADISHU, Somalia — An Associated Press investigation has found that a large amount of food sent by the U.N. to Somalia's capital during last year's famine never reached the starving people it was intended for.

The AP's three-month investigation reveals various shortcomings, some of which the U.N.'s World Food Program says it is already addressing by changing procedures.

Some of the WFP supplies went to the black market, some to feed livestock. One warehouse full of rations was looted in its entirety by a Somali government official. And across the city, feeding sites handed out far less food than records indicate they should have.

Britain estimates between 50,000 and 100,000 people died in Somalia's famine. The U.N. has requested $1.5 billion for Somalia this year, partly to prevent a return of famine.
