In this Tuesday, July 26, 2011, photo, a malnourished child waits outside a makeshift shelter a refugee camp for internally displaced people in Mogadishu, Somalia. The U.N. will airlift emergency rations this week to parts of drought-ravaged Somalia that militants banned it from more than two years ago — a crisis intervention to keep hungry refugees from dying along what an official calls the "roads of death." The foray into the famine zone is a desperate attempt to reach at least 175,000 of the 2.2 million Somalis whom aid workers have not yet been able to help. Tens of thousands already have trekked to neighboring Kenya and Ethiopia, hoping to get aid in refugee camps.
