JUBA, Sha'ban 4, 1436, May 22, 2015, SPA -- South Sudan's government said on Friday it had wrested control of oil-producing Upper Nile State, the scene of heavy fighting in recent days, from rebel fighters, Reuters reported. South Sudanese rebels said on Tuesday they had captured a refinery near a major oilfield in Upper Nile State, where fighting has flared in recent days, and told firms there to shut down operations and evacuate their staff in expectation of a full-fledged assault. But the government said in a statement that its forces were now in full control of Upper Nile. -- SPA 20:07 LOCAL TIME 17:07 GMT www.spa.gov.sa/w
