The UAE–Ethiopia–RSF Axis Is Reshaping Sudan’s War and Endangering the Horn of Africa

By Alula Frezghi

Sudan’s civil war is entering a more dangerous phase, one defined less by frontlines than by corridors. The latest clashes in the Blue Nile region, where Sudanese officials allege that Rapid Support Forces (RSF) fighters crossed from Ethiopian territory and deployed drones launched from inside Ethiopia have revived an uncomfortable question that has lingered since the war began:

Is Ethiopia, under Prime Minister Abiy Ahmed, quietly enabling the RSF’s war effort?

The evidence remains contested. But the pattern is increasingly difficult to dismiss.

What is emerging is not a single border incident or a tactical misstep. It is a wider geopolitical configuration, an influence system built on weakening states, empowering proxies, and operating through deniable logistics. Call it a fragmentation strategy: power exercised not by occupation, but by corridors.

At its center is a volatile alignment, the UAE, Ethiopia, and the RSF whose consequences are now radiating across the Horn of Africa.

A Border Clash That Reveals a System

Sudanese military officials claim RSF and SPLM-N fighters crossed into Sudan near Yabus, and that drones used in the fighting were launched from Ethiopia’s Benishangul-Gumuz region, from facilities allegedly linked to the United Arab Emirates. These claims have not been independently verified. But they are not implausible.

For months, analysts have warned that Ethiopia’s western frontier was becoming a pressure point, porous, under-governed, and increasingly militarized. The question is not whether Ethiopia is fighting for the RSF. It is whether Ethiopia has become a transit state for the RSF’s external backers.

That question leads directly to Abu Dhabi.

The UAE’s Proxy Model Reaches the Blue Nile

The UAE’s role in Sudan’s war is no longer seriously disputed. Emirati weapons, drones, financing, and logistics have sustained the RSF’s campaign against Sudan’s national army. But proxy wars require infrastructure: airspace, land routes, staging areas, and political tolerance.

Those options are narrowing. Chad has tightened controls. Egypt is hostile to RSF ambitions. Libya is unreliable. That leaves Ethiopia, a state emerging from internal war, dependent on Gulf capital, and struggling to secure its peripheries.

This is how proxy leverage works: not through alliance, but through vulnerability.

Ethiopia’s Role: Enabler, Not Belligerent

Available reporting stops short of accusing Ethiopia of sponsoring the RSF as a combatant. Addis Ababa is not deploying troops, issuing commands, or formally backing Hemeti’s forces.

But the more consequential role is quieter.

Ethiopia appears to be functioning as a corridor, a permissive environment through which RSF-linked supplies and technology can move. Intelligence leaks and satellite imagery cited by regional analysts point to an expanding Emirati footprint in Benishangul-Gumuz, a region already destabilized by inter-ethnic violence and proximity to the Grand Ethiopian Renaissance Dam.

This is not policy born of strength. It is accommodation born of constraint.

As one analyst noted, Ethiopia appears “less motivated by incentives than by pressure from the UAE.” That distinction matters. Pressure does not erase agency—but it does shape risk tolerance.

Three Dangerous Consequences

This emerging axis is not merely logistical. It carries destabilizing implications for the entire region.

First, it risks drawing Eritrea into Sudan’s war.
Eritrea is aligned with Sudan’s army and views RSF expansion as an existential threat. RSF operations enabled through Ethiopian territory would almost certainly provoke a response direct or indirect from Asmara. That is how localized wars become regional ones.

Second, it threatens Ethiopia’s own internal stability.
Benishangul-Gumuz is volatile. Amhara remains unstable. Tigray is fragile. Oromia is unresolved. A proxy conflict on Ethiopia’s western border would stretch an already overextended state. Fragmentation abroad feeds fragmentation at home.

Third, it destroys Ethiopia’s credibility as a mediator.
Addis Ababa once positioned itself as a diplomatic anchor of the Horn. Today, it is viewed with suspicion by Sudan, Eritrea, Egypt, and key regional bodies. A mediator cannot also be a corridor for weapons.

Fragmentation Versus Sovereignty

Sudan’s war is not only a Sudanese tragedy. It is the epicenter of a regional contest between two models.

On one side are states defending territorial integrity and resisting proxy warfare, Sudan’s army, Eritrea, Egypt, and others. On the other are actors advancing influence through deniability, militias, and fragmented authority, the RSF, its foreign backers, and permissive transit states.

The UAE–Ethiopia–RSF alignment is the most dangerous expression of this divide because it blurs the line between neutrality and complicity.

A Region at the Edge

The Horn of Africa is entering a perilous moment. Sudan is collapsing. Ethiopia is fragile. Eritrea is vigilant. Gulf rivalries are intensifying. And the RSF is fighting for survival.

The central danger is not a single allegation. It is the normalization of ambiguity, where corridors replace borders, proxies replace policy, and accountability disappears into logistics.

If left unchecked, this model could ignite a regional conflict far more destructive than the wars that came before.

What Must Be Done

Stability now depends on clear choices:
• Expose and disrupt proxy supply corridors
• Pressure Ethiopia to secure and close its western transit routes
• Prevent Eritrea from being dragged into Sudan’s war
• Defend Sudan’s territorial integrity
• Restore trust among Horn states through transparency, not denial

The alternative is a fragmented Horn of Africa, defined by proxy wars, weakened states, and permanent instability.

Fragmentation thrives in the shadows.
It is time to turn on the lights.
