Sudanese conflict in South Kordofan and Blue Nile

The Sudanese conflict in South Kordofan and Blue Nile was an armed conflict in the Sudanese states of South Kordofan and Blue Nile between the Sudanese Armed Forces (SAF) and the 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 agreement 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 two million people have been affected by the conflict, with more than 500,000 having been displaced and about 250,000 of them fleeing 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.

With the overthrow of al-Bashir in April 2019 following months of protests, the SRF announced a three-month ceasefire, hoping to facilitate a Sudanese transition to democracy. This led to the beginning of peace negotiations between the rebels and the new interim government. The Sudanese peace process was formalised with the August 2019 Draft Constitutional Declaration, signed by military and civilian representatives during the Sudanese Revolution, that mandates that a peace agreement be made in South Kordofan and Blue Nile (and in Darfur) within the first six months of the 39-month transition period to democratic civilian government.

On 31 August 2020, a comprehensive peace agreement was signed in Juba, South Sudan, between the Sudan's transitional government and the Sudan Revolutionary Front. The Sudan People's Liberation Movement-North led by Abdelaziz al-Hilu and Sudan Liberation Movement/Army led by Abdul Wahid al-Nur refused to sign the agreement.

An agreement was reached between the transitional government and the SPLM-North al-Hilu rebel faction on 3 September 2020 in Addis Ababa to separate religion and state and not discriminate against anyone's ethnicity in order to secure the equal treatment of all citizens of Sudan. The declaration of principles stated that “Sudan is a multi-racial, multi-ethnic, multi-religious and multi-cultural society. Full recognition and accommodation of these diversities must be affirmed. (...) The state shall not establish an official religion. No citizen shall be discriminated against based on their religion.”

Background
Although South Kordofan and Blue Nile are north of the Sudan–South Sudan border, many of their residents (particularly in the Nuba Mountains) identify with South Sudan with many of them having fought alongside the southern rebels during the Second Sudanese Civil War.

South Kordofan and Blue Nile were not allowed to participate in the January 2011 referendum to create South Sudan, and the "popular consultation" process they were promised also failed to take place.

According to satellite imagery, during early spring 2011, Sudan elevated dirt roads needed for tank transportation and in March 2011 it started deploying police and military installations in the area.

May 2011 Abyei conflict
In May 2011, ahead of South Sudan's scheduled independence, tensions rose around the status of the Abyei Area, an oil-rich region that was statutorily part of both South Kordofan and Northern Bahr el Ghazal states. As South Kordofan was slated to remain with Sudan while Northern Bahr el Ghazal was seceding together with the rest of what was then Southern Sudan Autonomous Region, the status of Abyei was unclear, and both Khartoum and Juba claimed the area as their own.

On 19 May 2011, militants reportedly affiliated with the Sudan People's Liberation Army attacked a convoy of mixed Sudanese Army and UNMIS vehicles 10 km north of Abyei town as they withdrew from the area's administrative centre, drawing condemnation from both the Sudanese government and the United Nations.

At least 15 Sudanese tanks entered Abyei town on 20 May, beginning large-scale fighting in Abyei. By 22 May, the Sudanese military had seized control of the town, and most of Abyei's residents had fled south toward Bahr el Ghazal. Both the Sudanese government and the government of Southern Sudan accused one another of violating the terms of the Comprehensive Peace Agreement.

In June 2011, an African Union panel headed by former South African president Thabo Mbeki tried to de-escalate the situation through north–south talks in the Ethiopian capital Addis Ababa. On 20 June, the parties agreed to demilitarize the contested area of Abyei, and UN peacekeepers were deployed as part of United Nations Interim Security Force for Abyei on 27 June. The agreement details how a new Abyei administration council would replace the one dissolved by president Omar al-Bashir in May 2011. Its chief shall be picked by the SPLM but must be approved by the northern National Congress Party (NCP). The deputy however, would be nominated by the NCP and endorsed by SPLM. Three of the five heads of the departments of the administrative council would be nominated by the SPLM and the remaining two by the NCP. A police service would be established for the region, with the size and composition determined by a joint committee co-chaired by northern and southern officials. The US Secretary of State Hillary Clinton and United Nations Secretary-General Ban Ki-moon welcomed the accord but said the real test would be how both sides would implement the deal.

On 21 June, a statement was attributed to the NCP's official in charge of the Abyei file, Didiri Mohamed Ahmed, as saying that there was an understanding reached at the Addis Ababa meeting between the two parties that South Sudan would concede future ownership of Abyei to Sudan. However, the spokesman of SPLA, Philip Aguer, told the press that the statement from the NCP senior official was incorrect.

June
On 5 June 2011, armed conflict broke out between the government of Sudan and the Sudan People's Liberation Movement–North (SPLM–N) in South Kordofan, ahead of the scheduled independence of southern Sudan on 9 July. The Sudanese Army said that the SPLA launched an attack on a police station and stole weapons prompting a response. The SPLA claimed that the Sudanese Army attempted to disarm their units by force. That day, the Justice and Equality Movement (JEM) rebel group claimed to have destroyed an army camp in the area of Jama, South Kordofan, killing 38 soldiers and wounding other 27.

On 14 June, the UN accused the Sudanese government of carrying out an "intensive bombing campaign" near the north–south border which has led to "huge suffering" for civilians in South Kordofan. Some 140,000 people fled the fighting. Aid agency offices were looted, churches were ransacked and buildings destroyed. Aid workers said that ethnic Nubans are being targeted by the Sudanese Army and Arab militias. This was denied by Rabbie Abdelattif Ebaid, an adviser to Sudan's information minister, who said that only rebel fighters were being targeted.

On 15 June, US President Barack Obama called for a ceasefire urging both the north and south to "live up to their responsibilities" to prevent a return to civil war. The head of the Anglican church, Archbishop of Canterbury Rowan Williams said: "The humanitarian challenge is already great, and the risk of another Darfur situation, with civilian populations at the mercy of government-supported terror, is a real one".

On 19 June, Sudanese president Omar al-Bashir accused the SPLM-N of "betrayal" in South Kordofan. "If they want war...we will show them practically like what happened in Abyei and South Kordofan" Bashir said. "It is better that they [SPLM-N] come to us in good terms and we will be better than them," he added. The Sudanese Army said that it would continue its military campaign in South Kordofan, which included aerial bombardment, until it crushes the rebellion led by former deputy governor and leading SPLM-N figure Abdelaziz al-Hilu. Fighting intensified around the state capital of Kadugli.

The following day, UN Undersecretary-General for Humanitarian Affairs Valerie Amos called for an independent investigation into atrocities possibly committed during the conflict. Amos said the Government of Sudan should lift its restrictions on access to the region.

They also called on the United Nations Security Council to impose a no-fly zone over Blue Nile, Darfur, and South Kordofan.

The declaration of principles stated that 'Sudan is a multi-racial, multi-ethnic, multi-religious and multi-cultural society. Full recognition and accommodation of these diversities must be affirmed.

Don't bring them [Rebels] back alive. We have no space for them". An army commander standing near Haroun then says: "Don't bring them back, eat them alive" amid laughter by the group in the video. Haroun follows with "Don't create an administrative burden for us [by bringing back prisoners alive]".

The United Nations High Commissioner for Human Rights Navi Pillay warned that the comments by the Governor could amount to "violations of human rights and international humanitarian law in South Kordofan and Blue Nile states". She followed with "Such comments are extremely worrying in this context and could amount to incitement.".

The Sudanese Government has since claimed that Mr. Haroun, who has already been indicted for war crimes and crimes against humanity by the International Criminal Court (ICC) for his alleged role in the previous conflict in Darfur, was simply trying to boost the soldiers' morale. Mr Haron however, has called the video a fabrication, accusing al-Jazeera of editing the video to distort what he had said and vowed to sue the news channel.

Ms. Pillay said that witnesses who have visited the Nuba mountain region, mainly inhabited by the Nuba people and located in Southern Kordofan, have been reporting the burning of villages and killing of civilians in "an apparent scorched-earth policy." "We know very little about the scale of the military operation in Southern Kordofan, as we have been denied access to the area," she said. "But as far back as August last year, we found that human rights violations that could amount to crimes against humanity or war crimes have taken place in Southern Kordofan.".

Emigration
Following what Yasir Arman, leader of SPLA-N and the UN have described as a "scorched earth policy" more than 105,000 Sudanese refugees from the states of Southern Kordofan and Blue Nile have sought refuge in South Sudan. An additional 30,000 refugees fled Blue Nile into nearby Ethiopia.

The Office of the United Nations High Commissioner for Refugees (UNHCR) and its partners started providing basic assistance to more than 16,000 refugees who settled in Yida, South Sudan, after fleeing violence in the Nuba Mountains region, located in Sudan's Southern Kordofan state. Another 2,300 refugees have so far moved southwards to safer sites in Nyeel and Pariang to another UNHCR camps. Meanwhile, in South Sudan's Upper Nile state, where an influx of refugees from Sudan's Blue Nile state is continuing, relocation from border zones has been ongoing. About 86,000 Sudanese refugees fleeing attacks in Blue Nile state have relocated to the safety of formal sites in Doro and Jammam, Ms. Fleming said.

However, since the beginning of Sudanese border conflict in 2012 the UNHCR now considers the Yida refugee settlement as not safe for long-term stay due to its proximity to the volatile border zone. South Sudan authorities at central and local level are also urging refugee leaders to relocate, in line with the provisions of the 1969 OAU (now AU) Convention on Refugees. Article 2 stipulates that "for reasons of security, countries of asylum shall, as far as possible, settle refugees at a reasonable distance from the frontier of their country of origin".

August 2011 ceasefire
On 23 August 2011, President Omar al-Bashir announced a two-week unilateral ceasefire in the conflict while on a surprise visit to South Kordofan state. He said the government would continue to embargo foreign aid directed toward South Kordofan, and the only humanitarian access would be through the Sudanese Red Crescent. He said that after the two-week ceasefire, "the situation will be assessed on the ground".

Supranational organisations

 * African Union – On 29 June, AU Commission Chairperson Jean Ping called on both sides in South Kordofan "to immediately cease hostilities, to allow the access of humanitarian aid and the return of displaced people" and hailed a ceasefire agreement as "decisive" and "a good omen". The AU, led first by former South African President Thabo Mbeki and then by Ethiopian Prime Minister Meles Zenawi, attempted to mediate a solution to growing tensions in Blue Nile, but it failed to prevent the spread of the conflict.
 * 🇺🇳 United Nations – The United Nations Security Council voted on 3 June to demand that Sudan and Southern Sudan withdraw troops from the Abyei Area. Secretary-General Ban Ki-moon voiced support for efforts to end the conflict in late June 2011, saying on 29 June that Sudan and the SPLM-N must work quickly for a cessation of hostilities. A United Nations Mission in the Sudan human rights investigation in June and early July, prior to the mission's disbandment, found that "condemnation is insufficient" for the atrocities it said had been committed by the Sudanese military during the fighting, including attacks on UNMIS offices and personnel, though it also criticised the SPLM for violations. In August, the United States attempted to persuade the Security Council to pass a resolution condemning the violence, but it was blocked by Sudanese allies Russia and China. United Nations High Commissioner for Refugees António Guterres responded to the outbreak of violence in Blue Nile in September by saying both sides must work to prevent "yet one more refugee crisis" in the region. Ban also expressed concern over the violence.

Countries

 * 🇸🇸 South Sudan – On 22 May, South Sudan denounced the seizure of Abyei as an "act of war". Information Minister Barnaba Marial Benjamin denied claims by the Sudanese government that Juba was offering material support to SPLM-N fighters in the North on 31 August and asserted that the SPLM had severed all ties with the SPLM-N after independence. He expressed concern at the violence in Blue Nile on 2 September and called on the Sudanese government to launch a full investigation and endeavour to prevent the violence from spreading.
 * 🇺🇸 United States – Having condemned the military takeover of Abyei on 21 March, on 22 July, Ambassador to the United Nations Susan Rice accused the Sudanese military of perpetrating human rights violations in South Kordofan. Princeton Lyman, the US special envoy to Sudan, said on 10 August that Washington was concerned that fighting could spread to and involve newly independent South Sudan.
 * 🇫🇷 France – On 22 May 2011, France condemned the military takeover and demanded a Sudanese withdrawal from Abyei. France argued that Sudan's actions constituted a violation of 2005 peace agreement and of the Kadugli Accord signed in January, and that the conflict should be mediated by the African Union.
 * 🇨🇦 Canada – On 23 May 2011, the Canada's Foreign Affairs Minister, John Baird, condemned the "recent upsurge of violence in Abyei". Canada called for an immediate withdrawal by both sides, respect for human rights and avoidance of further escalation. Baird added that he hoped "Northern and Southern Sudan" would both "embrace the opportunity afforded by the African Union High-Level Implementation Panel to resolve the status of Abyei and other outstanding issues".
 * 🇬🇧 United Kingdom – On 22 May 2011, Foreign Secretary William Hague condemned the violence, saying that the actions were "clear violations of the CPA and cannot be justified" and calling for "all sides to cease hostilities immediately. All unauthorised forces should be withdrawn from the entire area of Abyei in accordance with past agreements by the parties."

NGOs
Groups such as Human Rights Watch and Amnesty International have expressed concern about the humanitarian situation.

In May 2012, researchers from the Humanitarian Policy Group at the Overseas Development Institute highlighted that the situation in South Kordofan was approaching crisis levels and called for stronger leadership and engagement from humanitarian actors, as well as a redoubling of diplomatic efforts to restart political dialogue in the hope of securing a lasting and peaceful resolution.
