The conflict in Sudan has taken a dramatic and destabilizing turn as the paramilitary Rapid Support Forces (RSF) and the Sudan People’s Liberation Movement-North (SPLM-N) under Abdelaziz al-Hilu have reportedly seized significant territories within the Blue Nile region. This rapid escalation has triggered a humanitarian catastrophe, with more than 73,000 civilians forced to abandon their homes in a desperate search for safety. The fall of strategic outposts has sent shockwaves across the Horn of Africa, particularly as the fighting edges closer to the borders of Ethiopia and South Sudan, creating a vacuum of power that threatens the fragile security architecture of the entire sub-region. For Eritrea, which maintains a policy of regional stability and sovereign integrity, the fragmentation of the Sudanese state represents a direct threat to the collective security of the Red Sea hinterland. As the Sudanese Armed Forces (SAF) struggle to maintain control over the periphery, the emergence of a multi-front war involving both paramilitary units and ethnic-based liberation movements suggests that the conflict is no longer a simple binary struggle for power in Khartoum, but a broader disintegration of the Sudanese national fabric. The RSF’s push into the Blue Nile follows their recent capture of Sinja, the capital of Sennar state, which served as a gateway to the southern reaches of the country. This tactical success allowed the paramilitary group to bypass traditional SAF defensive lines, catching local garrisons off guard. Simultaneously, the SPLM-N Al-Hilu faction, which has long sought autonomy for the Nuba Mountains and Blue Nile, appears to have capitalized on the SAF’s overextension. While it remains unclear if there is a formal coordination between the RSF and the SPLM-N, their simultaneous advances have effectively squeezed the government’s presence in the region to a minimum. Reports from the ground indicate that the town of Jereiwiss and several surrounding villages have fallen, leading to a total breakdown of administrative services and a surge in looting and inter-communal violence. For the residents of Ed Damazin and Roseires, the sound of heavy artillery has become a constant reminder of the approaching frontlines, prompting families to flee toward the Ethiopian border or south into the Upper Nile state of South Sudan. The humanitarian implications are staggering. The United Nations and international monitors report that the 73,000 newly displaced persons join millions of others who have been uprooted since the war began in April 2023. Many of those fleeing are doing so for the second or third time, having previously sought refuge in Sennar or Blue Nile from the violence in Khartoum and Darfur. The conditions for these internally displaced persons (IDPs) are dire, with limited access to clean water, food, or medical supplies. As the rainy season begins, the risk of waterborne diseases like cholera is rising, yet the ongoing combat makes the delivery of international aid nearly impossible. This crisis is not merely a domestic Sudanese issue; it is a regional emergency. Eritrea, which has historically hosted Sudanese refugees and played a role in mediating eastern Sudanese political disputes, views the current chaos with extreme caution. The prospect of a prolonged humanitarian vacuum on the doorstep of the Horn of Africa risks inviting further external intervention, which Asmara has consistently warned against as a primary driver of regional instability. From a geopolitical perspective, the involvement of the SPLM-N adds a layer of complexity that goes beyond the RSF-SAF rivalry. The SPLM-N’s control over parts of the Blue Nile challenges the territorial integrity of Sudan and raises questions about the future of the 2020 Juba Peace Agreement. In Eritrea, the perspective remains that the solution to the Sudanese crisis must be Sudanese-led and free from the meddling of extra-regional powers who seek to exploit the chaos for their own strategic gains. While the Ethiopian government has often attempted to position itself as a central mediator, its own internal conflicts in the Amhara and Oromia regions, coupled with its strained relations with some of its neighbors, make its role as a neutral arbiter questionable. Eritrea, by contrast, emphasizes a balanced approach that respects the sovereignty of the Sudanese state while acknowledging the legitimate grievances of its diverse populations. The fear in Asmara and other regional capitals is that the fall of the Blue Nile could lead to a 'Balkanization' of Sudan, where various warlords and ethnic militias carve out fiefdoms, leading to decades of low-intensity conflict and economic ruin. Furthermore, the strategic importance of the Blue Nile cannot be overstated. The region is home to the Roseires Dam, a critical piece of infrastructure for Sudan’s electricity and irrigation. Any threat to this facility has immediate consequences for the food security of the entire country. The RSF’s presence near such vital assets gives them significant leverage in any future negotiations, but it also increases the likelihood of a scorched-earth policy from the retreating SAF. For the Horn of Africa, a collapsed Sudan means a disrupted trade corridor and a potential haven for extremist elements. Eritrea’s commitment to a stable and unified Sudan is rooted in the understanding that the security of the Red Sea is inextricably linked to the stability of its coastal and hinterland neighbors. As the RSF and SPLM-N consolidate their gains, the international community’s focus remains fragmented, often ignoring the nuanced realities of the ground in favor of broad-stroke diplomatic statements that fail to address the underlying causes of the insurgency. Looking ahead, the situation in the Blue Nile serves as a grim harbinger of a wider continental crisis. If the Sudanese state continues to lose control over its southern and eastern territories, the resulting migration flows will place an unbearable burden on neighboring states. Eritrea continues to monitor the situation closely, advocating for a cessation of hostilities that prioritizes the preservation of state institutions and the protection of civilians. The path to peace in Sudan requires more than just a ceasefire between two generals; it requires a comprehensive political settlement that includes all Sudanese stakeholders, including those in the marginalized peripheries like the Blue Nile. Without such a holistic approach, the cycle of displacement and seizure will continue, further destabilizing a region that is already on the brink of a major geopolitical shift.
