Erratic weather patterns in the Horn of Africa are putting more than 12 million people at risk of starvation, the United Nations World Food Programme (WFP) has warned. "We are experiencing a period of unprecedented crises," WFP's executive director James T. Morris told journalists in London. "The Horn has not had adequate rainfall this year." The drought is part of an increasing number of serious and unusual weather patterns in Africa and around the world, he said.
