On September 2, 2011, Department Spokesperson Victoria Nuland addressed the escalating violence in the Blue Nile State of Sudan. In a press statement, Spokesperson Nuland said: "The United States is deeply concerned about the fighting that broke out September 1 between the Sudan Armed Forces (SAF) and the forces of the Sudan People's Liberation Movement/Army-North (SPLM/A-N) in Blue Nile State in Sudan, as well as the ongoing troop mobilization on both sides. We call on both parties to cease hostilities and for the SAF to end aerial bombings. We also call on both parties to protect civilians and engage in dialogue to prevent further escalation of violence. "These clashes in Blue Nile follow fighting that has been ongoing since June 5 between the SAF and SPLM/A-North in Southern Kordofan, about which we also remain deeply concerned. The United States continues to call on both sides to allow unfettered humanitarian access and human rights monitoring of affected populations in Southern Kordofan, as well as Blue Nile. "The spread of fighting into Blue Nile further highlights the urgent need for negotiations between the Government of Sudan and the Sudan People's Liberation Movement-North to reach a political settlement that brings peace and stability to Southern Kordofan and Blue Nile. In this regard we are particularly disappointed that there has been no follow through after the meeting between President Bashir and SPLM/N Chairman Malik Agar in Khartoum on August 21. We also reiterate the need for a peaceful relationship between Sudan and South Sudan and for resolution of outstanding issues between the two countries."
