Fighting Raises Tension Between Government, Rebel Force in South Sudan Dimo Silva Aurelio JUBA, SOUTH SUDAN - New fighting in South Sudan's Central Equatoria state this week is putting a strain on the country's fragile peace agreements. A spokesman for the rebel National Salvation Front (NAS) said a joint force composed of soldiers from the army and the former rebel SPLM-IO attacked NAS positions in Central Equatoria state beginning on Sunday. "They went and attacked our bases in Senema, that is around Ombaci, and also in Mediba around Morobo, and in Kajo-Keji Kala 2. They also attacked our forces, and we responded," NAS spokesman Samuel Suba told VOA's South Sudan in Focus. Two NAS soldiers were killed and three others wounded during the fighting, according to Suba. The casualty figure could not be verified by other sources. .
