The United Nations appealed on Friday for $166 million to feed and treat 1.7 million people facing starvation and disease in drought-ravaged Ethiopia. Bjorn Liungqvist, the U.N. acting humanitarian coordinator said the drought had mainly affected livestock farmers in the Horn of Africa country following the failure of rains. "The situation in the pastoral areas is most critical," Liungqvist said in a statement carried today by Reuters. The lack of rains in many parts of East Africa, including Kenya, Somalia and Ethiopia, has left around 6 million people on the brink of starvation, according to the United Nations.
