UNITED NATIONS (AP) - The U.N. warned Thursday that Ethiopia and its Horn of Africa neighbors may face drought and famine equivalent to the crisis in the mid-1980s, during which nearly 1 million people died of starvation. Poor and infrequent rains coupled with fighting in Sudan, Somalia, Eritrea and Ethiopia threaten to cause a major humanitarian catastrophe, said Carolyn McAskie, deputy U.N. emergency relief coordinator. She announced that Secretary-General Kofi Annan has named the head of the World Food Program, Catherine Bertini, to be his special envoy to draw public attention to the crisis and mobilize the necessary relief operation.
