South Sudan's VP Machar ousted as party head, say rivals

South Sudan's Vice President Riek Machar has been ousted as head of his party and the national armed forces, according to party rivals. They say Machar was deposed following a three-day gathering of senior members of the Sudan People's Liberation Army-in-Opposition (SPLM-IO). Machar was a pivotal figure in South Sudan's descent into civil war in 2013 and his removal could upset the delicate post-conflict balance in the country.
