CAIRO, Dhu-AlQa'dah 20, 1437, Aug 23, 2016, SPA -- South Sudan opposition leader, Riek Machar, is in Khartoum for medical treatment, Sudan's Information Minister Ahmed Bilal Osman told the state-run news agency SUNA on Tuesday, according to Reuters. President Salva Kiir sacked Machar from his post as vice president after a renewal last month of fighting between forces loyal to the long-time rivals that forced tens of thousands of people to flee. Machar withdrew to the bush and was picked up this month by U.N. peacekeepers, in the Democratic Republic of Congo, with a leg injury. An opposition spokesman had said the injury was not serious enough to require medical attention. However, on Tuesday, Sudan said he was having treatment there. "Sudan has received, lately, Dr. Riek Machar, for pure humanitarian reasons, especially his need for treatment and medical care," Osman said. "Dr. Riek Machar's health is stable currently and he will remain in the country under comprehensive healthcare until he leaves to a destination of his choice, to complete his treatment," he added. -- SPA 19:23 LOCAL TIME 16:23 GMT www.spa.gov.sa/w
