Sudanese Government Representative Suleiman Abdul Rahman (L) speaks during a news conference with Arab League Ambassador Salah Halima (2nd L), United Nations Envoy Haile Menkerios and African Union Representative Mahmoud Kan (R) after they signed a joint agreement to deliver aid to South Kordofan and the Blue Nile states in Khartoum August 5, 2012. Sudan agreed on Sunday to allow aid into two rebel-held southern border states where humanitarian groups say fighting has left civilians facing an impending famine. The move came a day after Sudan reached a deal with South Sudan over oil transit fees, a first step to ending a dispute which had brought the hostile neighbours close to war in April.
