On August 3, 2012 Act for Sudan and 95 other civil society organizations wrote a letter to the UNSC addressing the need for urgent aid to be delivered.
The Guardian wrote this:
Sudan has finally agreed to allow relief supplies into the two rebel-controlled border states of South Kordofan and Blue Nile, where aid agencies say fighting and denial of aid access for more than a year has left civilians facing a humanitarian disaster.
The agreement came the day after Sudan’s negotiating team reached a deal with South Sudan over oil transit fees, potentially resolving a dispute that has threatened a return to all-out war. The UN security council resolution 2046 had threatened both Juba and Khartoum with sanctions if they failed to conclude negotiations by early August.
