The Sudanese conflict in South Kordofan and Blue Nile (2011–present) is an ongoing armed conflict in the Sudanese southern states of South Kordofan and Blue Nile between the Army of Sudan (SAF) and Sudan People's Liberation Movement-North (SPLM-N), a northern affiliate of the Sudan People's Liberation Movement (SPLM) in South Sudan. After some years of relative calm following the 2005 deal which ended the second Sudanese civil war between the Sudanese government and SPLM rebels, fighting broke out again in the lead-up to South Sudan independence on 9 July 2011, starting in South Kordofan on 5 June and spreading to the neighboring Blue Nile state in September. SPLM-N, splitting from newly-independent SPLM, took up arms against the inclusion of the two southern states in Sudan with no popular consultation and against the lack of democratic elections. The conflict is intertwined with the War in Darfur, since in November 2011 SPLM-N established a loose alliance with Darfuri rebels, called Sudan Revolutionary Front (SRF).
As of October 2014, some 2 million people have been affected by the conflict, more than 500,000 have been displaced and about 250,000 refugees have fled to South Sudan and Ethiopia. In January 2015, fighting intensified as Omar al-Bashir’s government tried to regain control of rebel-held territory ahead of April 2015 general elections.
