Ethiopia’s Renewed War Raises Fears of a Wider Horn of Africa Crisis

Addis Ababa, (ANN) — Renewed fighting in northern Ethiopia has sharply increased concern that a domestic conflict could develop into a broader regional confrontation involving Eritrea, Sudan and Egypt, at a time when the wider Horn of Africa and Red Sea region is already facing multiple overlapping security crises.
The latest escalation follows the collapse of a fragile period of calm between Ethiopia’s federal government and the Tigray People’s Liberation Front (TPLF). Fighting intensified in September 2026 across Tigray and spread into parts of the neighboring Amhara and Afar regions. The TPLF has joined a wider alliance of Ethiopian armed opposition groups challenging Prime Minister Abiy Ahmed’s government.

Renewed fighting in northern Ethiopia
The current confrontation follows the 2022 Pretoria peace agreement, which ended the devastating 2020–2022 Tigray war. That agreement reduced large-scale fighting but left several political, territorial and security disputes unresolved.
In September, Tigrayan forces and allied groups seized several strategic locations, while Ethiopian federal forces launched counteroperations. Reports have also described fighting around airports and towns in Tigray, Amhara and Afar.

The humanitarian consequences are already significant. The Associated Press reported that medical facilities in northern Ethiopia had received hundreds of wounded people and that approximately 150,000 people had been displaced amid the latest fighting.

Ethiopia accuses Eritrea, Sudan and Egypt
A major concern is the increasingly international character of the dispute.
Ethiopia’s military leadership has accused Eritrea, Sudan and Egypt of supporting the TPLF-led opposition alliance. Those governments have rejected the allegations. Sudan has, in turn, accused Ethiopia of supporting armed groups fighting Sudan’s military, while Egypt has rejected allegations that it is interfering in Ethiopia’s internal conflict.

These accusations remain claims by the parties to the conflict and should not be treated as independently established facts.
Nevertheless, the diplomatic consequences have already become serious. On October 1, Ethiopia ordered the closure of its embassy in Eritrea and expelled 10 Eritrean diplomats. Eritrea subsequently announced that it was severing diplomatic relations with Ethiopia.

That development is particularly significant because Eritrea fought alongside Ethiopian federal forces during the previous Tigray war. Relations between the two countries subsequently deteriorated, including over Ethiopia’s ambitions for access to the Red Sea.

The Sudan connection
The war in Sudan adds another layer of risk.
Sudan has been fighting a devastating conflict between the Sudanese Armed Forces and the Rapid Support Forces since 2023. Ethiopia and Sudan have exchanged accusations over alleged support for armed groups operating across their border.
The renewed fighting in Tigray is occurring close to the Sudanese border, meaning that movements of fighters, refugees and weapons could potentially complicate the already unstable security environment. Analysts have warned that the Ethiopian and Sudanese conflicts could increasingly become interconnected.

The situation is therefore not simply a bilateral Ethiopian crisis. Developments on one side of the border can affect the other.
Egypt and the Nile dispute
Egypt’s involvement is particularly sensitive because of its long-running dispute with Ethiopia over the Grand Ethiopian Renaissance Dam (GERD) on the Blue Nile.
Cairo and Addis Ababa have disagreed for years over the operation and impact of the dam. The dispute has increasingly become connected to wider competition over regional security, water resources and influence in the Horn of Africa and Red Sea.

However, Egypt’s rejection of Ethiopia’s accusations is important. At present, publicly available reporting establishes the accusation and the denial, but it does not establish as fact that Egypt is directing or supporting the TPLF-led military campaign.
Why the Red Sea and Bab el-Mandeb matter
The geographical consequences could extend well beyond Ethiopia.
Northern Ethiopia lies close to Eritrea, Sudan and Djibouti, while Ethiopia’s strategic interests increasingly extend toward the Red Sea. Any serious confrontation between Ethiopia and Eritrea would therefore have implications for one of the world’s most strategically important maritime regions.
The Bab el-Mandeb Strait, connecting the Red Sea with the Gulf of Aden, is particularly important for international shipping. It is already affected by insecurity linked to the war in Yemen and attacks by the Houthi movement.
The Council on Foreign Relations has described the conflicts on both sides of the Red Sea as increasingly interconnected, noting that fighting in Ethiopia has expanded into Amhara and Afar while instability continues around the Red Sea and Yemen.

Somalia and the wider Horn
Somalia also sits within this wider security environment because of its location along the Gulf of Aden and near the Bab el-Mandeb maritime corridor.
A prolonged Ethiopian-Eritrean confrontation could place additional pressure on neighboring states, particularly if refugee movements increase, borders become militarized or competing regional powers begin supporting opposing armed actors.
The combination of Ethiopia’s renewed internal war, Sudan’s continuing civil war, tensions between Ethiopia and Eritrea, the Egypt-Ethiopia Nile dispute, instability in Somalia and the continuing conflict in Yemen creates an unusually interconnected security environment across the Horn of Africa and Red Sea.
A conflict with regional consequences
The immediate conflict remains fundamentally rooted in Ethiopia’s internal political and territorial disputes. But the involvement—or alleged involvement—of neighboring states could transform the crisis.
Chatham House has warned that the present conflict carries a risk of extending into Eritrea and Sudan, while the Council on Foreign Relations has described the wider Red Sea environment as a convergence of interconnected conflicts.
Chatham House +1
For now, it would be premature to describe the situation as a regional war. But the diplomatic rupture between Ethiopia and Eritrea, the accusations involving Sudan and Egypt, and renewed fighting involving the TPLF have substantially increased the risk that Ethiopia’s conflict could acquire a wider regional dimension.
