Ending a 19-year war, Angola's warring factions signed a ceasefire agreement today. Under the plan signed by top generals of the government and the National Union for the Total Independence of Angola (UNITA), fighting -- which began on the eve of Angola's independence from Portugal in 1975 -- will stop Wednesday. The truce will remain in effect until final details emerge as part of a United Nations-brokered peace treaty, which is scheduled to be signed Sunday. That accord aims to close the book on the civil war in Angola -- the longest and bloodiest battle in Africa. "The Angolan people have suffered for 20 years," said Alioune Blondin Beye, the U.N. special envoy to Angola today. "There is going to be no more killing in Angola."Post your opinion on theInternationalbulletin board.
