In news from Africa, the United Nations is warning a catastrophe is looming in Somalia in the wake of the U.S.-backed Ethiopian invasion. Over 200,000 people have fled the capital of Mogadishu since February. Many of the refugees now lack food and clean water. Cholera has struck hundreds in the Somali capital in the past month, and more than 400 people have died following a diarrhea epidemic. At least 14 people died in fighting in Mogadishu yesterday. A car bomb also exploded outside an Ethiopian military base.
