South Sudan's government said Saturday that fighting in the country's five-month civil war appeared to have stopped as a ceasefire with rebels came into effect following a peace deal. President Salva Kiir and rebel leader Riek Machar, a former vice president, met in the Ethiopian capital Addis Ababa on Friday, shook hands and prayed together, and agreed to order a halt to fighting within 24 hours -- or by Saturday evening. We have **t received any attacks since this morning,\" South Sudan's defence minister, Kuol Manyang, told AFP late Saturday.
