The Horn of Africa at a Strategic Crossroads: Ethiopia's Internal Crisis and the Rising Tensions with Egypt and Eritrea
The Horn of Africa at a Strategic Crossroads: Ethiopia's Internal Crisis and the Rising Tensions with Egypt and Eritrea
How renewed conflict inside Ethiopia is becoming entangled with the Nile, the Red Sea and the wider security architecture of the Horn of Africa
 |
| Egypt, Eritrea and Somalia are developing overlapping security interests as tensions with Ethiopia intensify, although they do not constitute a formal military alliance. |
On 1 October 2026, the African Union Commission issued an unusually direct warning over what it described as heightened tensions between Ethiopia, Eritrea and Egypt, calling on the three states to exercise “maximum restraint” and to preserve diplomatic channels. The statement came as renewed fighting in northern Ethiopia was rapidly developing into a regional security concern.
The developments since late September have made the warning increasingly difficult to dismiss as a conventional diplomatic dispute. Fighting has resumed in and around Tigray, several armed Ethiopian groups have formed a new alliance against the federal government, Ethiopia has closed its embassy in Eritrea and expelled Eritrean diplomats, and Eritrea has responded by severing diplomatic relations with Ethiopia. Addis Ababa has also accused Eritrea, Sudan and Egypt of supporting the opposition forces; all three countries have denied those allegations. On 3 October, Reuters reported that Ethiopian federal forces had retaken Alula Aba Nega Airport in Mekelle, the capital of Tigray, although fighting and political uncertainty remained.
For European observers, the significance of this crisis extends beyond the domestic politics of Ethiopia. The Horn of Africa borders the Red Sea and the Gulf of Aden, sits alongside one of the world's most important maritime corridors, and connects the security of the Nile Basin to the commercial routes leading toward the Suez Canal. The European Union itself extended the mandate of Operation ASPIDES through February 2027 to protect freedom of navigation in the Red Sea and surrounding waters, including the maritime approaches around Bab el-Mandeb.
The present crisis, therefore, should not be reduced to a simple confrontation between Ethiopia and its neighbours. It is better understood as the interaction of three overlapping processes: the growing strain on Ethiopia's federal political settlement; the country's increasingly important search for reliable access to the sea; and the emergence of a counter-balancing security alignment among Egypt, Eritrea and Somalia, each pursuing its own interests rather than acting as members of a formal military bloc.
I. Ethiopia's Internal Crisis: Strain on the Federal Bargain
The first key to understanding Ethiopia's external behaviour lies inside Ethiopia itself. The country's federal system, built around regional and ethnic political structures, has come under severe pressure over the past several years. The problem is not simply that Ethiopia contains several armed conflicts; rather, political competition, territorial disputes, regional military structures and the struggle over the distribution of federal authority increasingly reinforce one another.
This does not mean that Ethiopian federalism has simply “collapsed”. The more important development is that the political bargain underpinning the federation has become harder to sustain through negotiated compromise.
1. The erosion of the Pretoria peace settlement
The Pretoria agreement of November 2022 ended the large-scale Tigray war between the federal government and the Tigray People's Liberation Front (TPLF). Yet the agreement did not resolve every underlying dispute. Questions over territorial control, the return of displaced people, disarmament and the political status of contested areas remained difficult, particularly in and around western and southern Tigray.
By September 2026, the unresolved tensions had moved back into open armed confrontation. On 21 September, seven Ethiopian armed groups, including the TPLF, the Amhara Fano National Movement and the Oromo Liberation Army, announced the formation of the Ethiopian Peoples' Forces Alliance for Survival. The organisations had previously been divided by geography, ideology and, in some cases, by direct military confrontation. Reuters reported that the new coalition sought to remove Prime Minister Abiy Ahmed's government, although the groups themselves remained divided over territorial and political questions.

| On Friday, October 2, 2026, a group loyal to the Ethiopian federal government announced that they had secured full control of Mekelle Airport (Alula Aba Nega Airport) in the capital of the Tigray region, following a counter-attack against rebel forces. |
2. Amhara, Oromia and the multiplication of internal fronts
Tigray is not the only arena in which the Ethiopian federal system has come under pressure.
In Amhara, the Fano insurgency emerged after tensions between the federal government and regional forces intensified, particularly following Addis Ababa's decision to reorganise regional special forces. By 2023, fighting between federal forces and Fano militias had developed into a sustained insurgency.
Oromia presents a different but equally important challenge. The Oromo Liberation Army has continued an armed struggle against federal authorities, while violence and political tensions have also affected the relationship between Oromo and Amhara communities.
International Crisis Group warned as early as 2024 that conflicts in Amhara and Oromia, together with unresolved questions in Tigray, represented interconnected threats rather than isolated security problems. It argued that Ethiopia's three most powerful regional constituencies had increasingly developed competing political grievances toward the federal centre.
That fragmentation matters strategically because it limits the ability of Addis Ababa to separate domestic security from foreign policy. A government confronting several armed challenges simultaneously must also manage its relations with Eritrea to the north, Sudan to the west, Somalia to the east and Egypt farther downstream along the Nile.
In such an environment, the external strategic arena becomes inseparable from the domestic one.
3. Sea access and the search for strategic depth
One of the most consequential examples is Ethiopia's campaign to secure reliable access to the sea.
As a landlocked state since Eritrea's independence in 1993, Ethiopia has long depended heavily on neighbouring states for maritime trade. Prime Minister Abiy Ahmed has increasingly presented secure access to the sea as a strategic and economic necessity, while repeatedly stating that Ethiopia seeks a negotiated rather than military solution.
The issue became particularly controversial after Ethiopia signed a memorandum of understanding with Somaliland on 1 January 2024. Under the reported terms, Ethiopia would obtain a long-term lease over approximately 20 kilometres of coastal territory around Berbera for commercial and naval purposes, while Somaliland expected recognition of its independence. Somalia rejected the agreement as a violation of its territorial sovereignty.

| Ethiopia's search for reliable maritime access has become one of the central geopolitical questions in the Horn of Africa. |
The dispute subsequently moved into a different diplomatic framework. In December 2024, Ethiopia and Somalia signed the Ankara Declaration under Turkish mediation, reaffirming each country's sovereignty and territorial integrity while agreeing to pursue mutually beneficial arrangements that would give Ethiopia reliable and sustainable access to the sea under Somali sovereignty. The European External Action Service welcomed the agreement as a mechanism for de-escalation.
This evolution is important. Ethiopia's pursuit of maritime access can no longer be understood simply through the 2024 Somaliland memorandum. It has become a broader strategic question involving Eritrea, Somalia, Türkiye, the Red Sea states and outside powers.
The domestic significance of the issue is also important. Access to the sea is not merely a question of trade infrastructure. It has increasingly been incorporated into Ethiopian debates over sovereignty, development and national power. That gives the issue political importance at home while simultaneously increasing its sensitivity abroad.
II. The Emergence of a Counter-Balancing Alignment: Egypt, Eritrea and Somalia
The regional response to Ethiopia's strategic movement has not produced a formal alliance in the conventional military sense. What has emerged instead is a growing pattern of strategic coordination among Egypt, Eritrea and Somalia, driven by different but increasingly overlapping concerns.
The relationship is therefore better described as a counter-balancing alignment than as a unified anti-Ethiopian bloc.
1. Egypt's dual security perspective: the Nile and the Red Sea
For Egypt, Ethiopia presents two strategically connected questions: water security in the Nile Basin and maritime security in the Red Sea.

| Egypt's dual security perspective: the Nile and Bab el-Mandeb Strait map |
The Grand Ethiopian Renaissance Dam has been the centrepiece of the first dispute. Ethiopia inaugurated the GERD in September 2025, describing it as a major development and energy project. Egypt, however, has continued to object to unilateral Ethiopian management of the dam and has sought a legally binding framework governing its operation, particularly during prolonged drought conditions.
This disagreement has acquired a wider geopolitical dimension because the Nile is no longer the only arena in which Cairo and Addis Ababa compete over strategic space.
The Ethiopian search for maritime access brings the dispute closer to the Red Sea. From Cairo's perspective, the security of the Bab el-Mandeb–Red Sea–Suez corridor cannot easily be separated from developments in the Horn of Africa. The importance of that corridor is also directly relevant to European economies. In 2026, the EU continued its ASPIDES maritime operation to protect commercial shipping from threats around the Red Sea and Bab el-Mandeb.
Egypt's expanding security relationship with Somalia must be understood in this wider context. Egypt and Somalia signed a military cooperation protocol in August 2024, while Cairo later announced its intention to contribute troops to AUSSOM, the African Union Support and Stabilization Mission in Somalia. The AU subsequently incorporated Egyptian troops into the mission's deployment planning.
By 2026, Egypt remained actively engaged in the AUSSOM framework and continued to describe Somalia's stability as central to the wider security of the Horn and the Red Sea.
From Cairo's perspective, therefore, the Nile and the Red Sea are not two separate strategic theatres. They increasingly form a single security arc.
2. Eritrea's changing relationship with Ethiopia
The Eritrean dimension is even more complicated because Ethiopia and Eritrea were once strategic partners.
During the Tigray war of 2020–2022, Eritrea fought alongside Ethiopian federal forces against the TPLF. Relations subsequently deteriorated, however, particularly after Eritrea was excluded from the negotiations that produced the Pretoria agreement and as disagreement over Ethiopia's maritime ambitions intensified.
Ethiopia's renewed interest in Red Sea access has generated particular sensitivity in Asmara because Eritrea controls the strategically important ports of Assab and Massawa. Ethiopia has repeatedly insisted that its search for sea access should be negotiated peacefully, and Prime Minister Abiy Ahmed explicitly rejected the idea of war with Eritrea in 2025. Nevertheless, the strategic mistrust surrounding access to the Red Sea has continued.
That mistrust reached a new stage in October 2026. Ethiopia closed its embassy in Asmara and expelled ten Eritrean diplomats, accusing Eritrea of hostile activity and support for opposition forces. Eritrea responded by severing diplomatic relations with Ethiopia. The deterioration occurred alongside renewed fighting in Tigray and accusations by Ethiopian officials that Eritrea was supporting the armed opposition. Asmara has denied those allegations.
The relationship is therefore no longer simply the story of two former allies drifting apart. Eritrea's own security calculations are increasingly tied to the wider question of who controls the strategic geometry of the northern Horn of Africa and the Red Sea.
3. Somalia and the question of territorial sovereignty
Somalia occupies the third corner of this emerging strategic geometry.
Mogadishu's reaction to the 2024 Ethiopia-Somaliland memorandum was fundamentally about sovereignty. Somalia regarded Somaliland as part of its territory and rejected any arrangement that would allow Ethiopia to secure a strategic coastal presence through a deal with Somaliland independent of the federal government.
The Ankara Declaration temporarily shifted the dispute from direct confrontation toward negotiations, but it did not remove the underlying strategic issue: Ethiopia still seeks secure maritime access, while Somalia insists that any arrangement must remain under Somali sovereign authority.
Relations between Somalia and Egypt have consequently deepened. In October 2024, Egypt, Eritrea and Somalia held a tripartite summit in Asmara and agreed to strengthen coordination on regional security while emphasizing sovereignty and territorial integrity. Reuters described the arrangement as a further tightening of relations between the three states amid Ethiopia's disputes with its neighbours.
This does not mean that Cairo, Asmara and Mogadishu share identical objectives. Somalia's priority is territorial sovereignty and state survival; Egypt's interests are strongly connected to the Nile and Red Sea; Eritrea's calculations are shaped by its own security relationship with Ethiopia and the Red Sea coastline.
What connects the three states is not a single strategic doctrine, but a convergence of interests in preventing any unilateral restructuring of the regional balance around Ethiopia.
III. The Wider Geostrategic Consequences
The danger of the current crisis lies not only in the possibility of another Ethiopian civil war. The greater risk is that domestic conflicts, interstate rivalry and maritime competition begin reinforcing one another.
1. The growing risk of proxy dynamics
It is still important to distinguish between documented military involvement and accusations of external support.
Ethiopia has accused Eritrea, Sudan and Egypt of assisting opposition forces linked to the renewed fighting in the north. Eritrea, Sudan and Egypt have denied the accusations. The available evidence does not establish a single coordinated external campaign directed against the Ethiopian government.
Yet the political significance of these accusations is considerable.
Once neighbouring governments begin interpreting internal Ethiopian conflicts through an interstate security lens, domestic armed groups can acquire regional importance even without forming formal alliances with foreign governments. Border areas become more difficult to manage, military mobilisation becomes more likely and diplomatic disputes can increasingly be interpreted as extensions of domestic conflict.
This is how a local conflict can gradually become a regional security problem without any government formally declaring war.

2. Militarisation of the Red Sea and Bab el-Mandeb
The Horn of Africa's land conflicts are unfolding alongside an already unstable maritime environment.
The Red Sea, Bab el-Mandeb and the Gulf of Aden have become central theatres of international naval operations because attacks on commercial shipping have disrupted one of the principal maritime routes linking Europe, the Middle East and Asia. The EU's continued Operation ASPIDES illustrates how European governments increasingly regard security in these waters as an issue of direct strategic interest rather than a distant regional concern.
Any additional military tension along the African side of the Red Sea therefore has consequences beyond Ethiopia and its immediate neighbours.
A more heavily militarised environment increases the possibility of miscalculation between naval forces, complicates commercial navigation and adds another layer of risk to supply chains already affected by instability in Yemen and the wider Middle East.
The geography matters. The maritime corridor from the Gulf of Aden through Bab el-Mandeb and the Red Sea to Suez connects European trade directly to political developments in the Horn of Africa.
3. The limits of regional institutions
The African Union remains the most important continental institution capable of providing a diplomatic framework for de-escalation. Its 1 October statement demonstrated that the organisation is closely monitoring the deterioration and is prepared to support dialogue.
But the current crisis also exposes the limits of regional crisis management.
The AU must engage governments that are simultaneously parties to the disputes it is trying to mediate. IGAD faces a similarly difficult regional environment in which Ethiopia, Somalia, Sudan, South Sudan and other member states are dealing with overlapping security crises. Its September 2026 ministerial communiqué itself described growing instability in the Red Sea and Gulf of Aden and warned that disruptions to commercial shipping have regional and global consequences.
The institutional challenge is therefore not simply a lack of mediation initiatives. It is the difficulty of building a common regional security framework when individual states increasingly perceive one another through the prism of competing strategic interests.
4. The humanitarian dimension
The humanitarian consequences remain the most immediate cost of renewed conflict.
By late September and early October, aid organisations were already reporting large numbers of casualties and displacement linked to renewed fighting in northern Ethiopia. The Associated Press cited Médecins Sans Frontières reports of hundreds of wounded people treated in hospitals in the affected areas and estimated that around 150,000 people had been displaced.
The wider humanitarian burden is much larger. The International Organization for Migration's 2026 Ethiopia response plan identifies millions of displaced or returning internally displaced people and continued insecurity across Tigray, Amhara, Afar, Oromia and other regions.
This is particularly important for Europe because instability in the Horn of Africa has consequences beyond the battlefield. Conflict, displacement and economic deterioration can affect migration routes across the Red Sea, the Gulf of Aden and onward toward the Arabian Peninsula and Europe.
For that reason, the humanitarian crisis and the strategic crisis should not be treated as separate issues.
Conclusion: From an Ethiopian Conflict to a Regional Security System
The renewed crisis in the Horn of Africa is not adequately explained by a single dispute between Ethiopia and its neighbours. Its deeper structure lies in the interaction between Ethiopia's internal political fragmentation, unresolved post-war disputes, the strategic importance of the Nile, and Addis Ababa's determination to secure more reliable access to the sea.
The central analytical point is therefore not that Ethiopia's domestic crisis automatically produces external confrontation. Rather, internal fragmentation and regional competition are increasingly feeding into one another.
The seven-group armed alliance announced in September, the renewed fighting in Tigray, the collapse of diplomatic relations between Ethiopia and Eritrea, the continuing dispute with Egypt over the Nile and the emerging security coordination among Egypt, Eritrea and Somalia are all manifestations of this wider interaction.
At the same time, it would be misleading to describe Egypt, Eritrea and Somalia as a fully integrated anti-Ethiopian alliance. Their interests overlap, but they are not identical, and each government retains its own calculations and constraints.
The more consequential development is the emergence of a new regional security geometry in which the Nile Basin, the Horn of Africa and the Red Sea increasingly form one interconnected strategic space.
For Europe, this matters because the effects do not stop at the African coastline. The same geography links the conflict zones of Ethiopia and Sudan to the maritime routes of Bab el-Mandeb and Suez, the security of international shipping, migration across the Red Sea and the wider stability of Europe's southern neighbourhood.
The immediate priority, therefore, is not simply to prevent another Ethiopian civil war. It is to prevent the fragmentation of Ethiopia's internal conflict from becoming permanently embedded in the wider security architecture of the Red Sea and the Horn of Africa.
That distinction may ultimately determine whether the current crisis remains a series of interconnected conflicts—or develops into a genuinely regional confrontation.
The renewed fighting in Tigray has therefore become more than a local dispute. Consequently, it is possible to speak of the likelihood of it being a new conflict as a threat to a broader regional war because it intersects with Eritrean-Ethiopian tensions, the Sudanese conflict, disputes over Red Sea access and the continuing strategic rivalry surrounding the Nile.
