GAROWE, Somalia -- The U.N. and aid agencies are warning of a possible catastrophe in Somalia, where a severe drought has plunged millions of Somalis into crisis.

The drought has increased the number of malnourished children, displaced thousands of people and killed thousands of animals. Officials in a central Somali region said 18 people had died of drought-related effects.

The U.N. says the malnutrition rate among children has jumped to 30 percent in Somalia's southern Juba region, a figure double the emergency threshold. Food prices have soared up to 80 percent.

The drought is the latest in a long line of problems for Somalia, which has been mired in conflict since 1991.
