South Sudan rebel leader Riek Machar has left Khartoum for South Africa to seek medical treatment.
His departure came just two months after he went to the Sudanese capital for medical attention.
The former South Sudan first vice-president addressed the press at the Khartoum airport where he thanked the government of Sudan the hospitality before his departure.
The rebel leader recently declared that he would work to bring down the government of President Salva Kiir, sparking a diplomatic row between Juba and Khartoum, but the latter says it will not allow any aggression or opposition activities against South Sudan from its territories.
Dr. Machar was treated at a Khartoum hospital in August after he fled South Sudan following the eruption of war in the new state in July.
