ADDIS ABABA — Eritrea has officially cut off diplomatic relations with neighboring Ethiopia, marking a dramatic and dangerous escalation in a long-simmering geopolitical conflict rooted in territorial disputes, historical grievances, and mutual accusations of state-sponsored interference.
The abrupt diplomatic rupture comes as intense fighting flares once again across northern Ethiopia, pitting federal government troops against a newly formed opposition alliance. Addis Ababa has openly accused Asmara of providing critical military backing to the rebel factions. These escalating clashes represent the most severe military engagement in Ethiopia since the devastating 2020–2022 civil war, a catastrophic conflict that claimed the lives of hundreds of thousands of people and left millions displaced.
International analysts are warning that the ripple effects of this renewed violence could extend far beyond Ethiopia’s borders, potentially fueling broader, catastrophic unrest across the Horn of Africa—a strategically vital region already plagued by multiple interrelated and compounding conflicts.
Why Did Eritrea Break Off Ties With Ethiopia?
The formal severing of diplomatic ties was announced by Eritrea on Thursday, arriving as a direct tit-for-tat response after Addis Ababa announced that it would unilaterally close its embassy in Asmara and expel 10 Eritrean diplomats.
In an official statement released by Eritrea’s Ministry of Foreign Affairs, the government stated that Ethiopia’s aggressive administrative and diplomatic actions had left Asmara with "no option but to reciprocate in kind and sever all diplomatic ties with Ethiopia." The ministry forcefully accused the Ethiopian government of pursuing a multi-year "agenda of incessant hostility." Among the specific grievances cited by Asmara were alleged Ethiopian infringements upon Eritrean coastal areas and the systematic arming of domestic political and military fighters opposed to the administration in Addis Ababa.
Conversely, Ethiopia has consistently maintained that Eritrea is actively harboring and backing armed groups dedicated to overthrowing the federal government. Both neighboring states have categorically rejected the other’s accusations.
This rapid diplomatic breakdown follows months of steadily deteriorating relations. The renewed friction has been driven largely by landlocked Ethiopia’s aggressive push for sovereign access to the Red Sea—a strategic objective that alarms Eritrean leadership—alongside mounting allegations that Asmara is providing logistical and military support to the Tigray People’s Liberation Front (TPLF). The TPLF currently leads the Ethiopian Peoples’ Forces Alliance for Survival, an umbrella opposition rebel alliance actively fighting federal forces for control of strategic territories in northern Ethiopia.
Have Ethiopia’s Ties With Egypt and Sudan Been Hit, Too?
The diplomatic crisis is not confined to Asmara. Ethiopia has also formally accused Egypt and Sudan of joining forces with Eritrea to back the Tigrayan rebel forces, dealing a heavy blow to already fragile and strained relations with both downstream and neighboring nations.
Ethiopia has long found itself at loggerheads with Egypt concerning the construction, filling, and operation of the multi-billion-dollar Grand Ethiopian Renaissance Dam (GERD) project on the Blue Nile. Cairo views the monumental dam as an existential threat to its national water security and its historic share of Nile River waters.
This underlying tension has quickly manifested in diplomatic expulsions. State-linked media in Egypt reported that Cairo ordered an Ethiopian diplomat to leave the country on Thursday. The move came in immediate retaliation after Addis Ababa earlier expelled an Egyptian diplomat from Ethiopian soil.
An Egyptian state-linked broadcaster, Al-Qahera News, quoted a senior Egyptian official who condemned Ethiopia’s initial expulsion of the Egyptian diplomat as "regrettable and unjustified," confirming that Cairo felt compelled to respond in strict accordance with "the principle of reciprocity."
Meanwhile, the unfolding conflict has severe implications for Sudan, whose current military-backed government is locked in its own brutal internal civil conflict. Khartoum has accused Ethiopia of sheltering and backing rival rebel forces operating inside Sudan—allegations that the Ethiopian government firmly denies.
Ahmed Soliman, a senior research fellow at the Chatham House think tank’s Africa program, highlighted the interconnected nature of these geopolitical fault lines. He noted that the domestic conflicts in Ethiopia and Sudan have become deeply intertwined, with respective governments accusing each other of harboring and equipping opposition forces. Furthermore, Egypt has been actively drawn into the wider regional escalation due to its enduring enmity with Ethiopia over the Nile basin.
What Is Happening in Northern Ethiopia?
On the ground, Tigrayan-led rebel forces have engaged in fierce, sustained clashes with Ethiopian government-backed forces across the country’s northern tier since last week. The heaviest fighting is currently concentrated across three volatile regions: Tigray, Amhara, and Afar.
Reporting from the ground, Al Jazeera’s bureau chief in Ethiopia, Mohammed Taha Tawakel, indicated that federal government-aligned forces have made significant territorial gains within the Tigray region. These forces have successfully secured control of several key towns and are steadily closing in on Mekelle, the regional capital.
Further east in the Afar region, a pro-government local armed group announced on Thursday that it had successfully recaptured the strategic town of Erebti, which had fallen under rebel control earlier in the week. The pro-government militia publicly thanked the Ethiopian national military for providing "magnificent air support" and declared its intention to press forward with further military advances.
Despite these tactical pro-government gains, Tawakel reported that rebel forces continue to maintain what he described as a "strong rear link with Eritrea" along the highly porous international border. This cross-border connection remains a vital lifeline for the insurgent groups.
The intensification of hostilities has sparked profound humanitarian anxiety. There are growing fears that active combat will soon spill over into densely populated urban centers within Tigray, including historic cities such as Adwa, Axum, Shire, and Mekelle. Local residents have already begun fleeing the violence, seeking refuge in neighboring Amhara and Afar.
The insecurity also appeared to breach the national capital of Addis Ababa for the first time early Thursday morning, when a sudden explosion was reported in the vicinity of the Ministry of Defence. International news agencies, including AFP, cited a diplomatic source suggesting that small tactical drones were the most probable cause of the blast. While the Ethiopian national army commands a significantly larger and more advanced arsenal of unmanned aerial vehicles, conflict monitoring organizations such as ACLED note that rebel factions have previously demonstrated the capability to deploy drones against airbases and critical infrastructure across various parts of the country.
What Are the Roots of the Ethiopia-Eritrea Dispute?
The historical relationship between Ethiopia and Eritrea has been characterized by profound fragility and decades of conflict. In 1962, Ethiopia formally annexed Eritrea, sparking a protracted 30-year armed struggle for independence led by figures including Eritrea’s current President, Isaias Afwerki. Independence was officially achieved in 1993, but peace was short-lived; the two nations subsequently fought a brutal border war between 1998 and 2000 that resulted in tens of thousands of casualties.
A major geopolitical shift occurred in 2018 when Ethiopian Prime Minister Abiy Ahmed assumed power and initiated a historic peace process, formally ending decades of hostility and restoring diplomatic relations with Asmara—an effort that earned Prime Minister Abiy the Nobel Peace Prize. During the height of Ethiopia’s 2020–2022 civil war, Eritrea even aligned its forces with Addis Ababa to fight against the TPLF.
However, analysts point out that Prime Minister Abiy’s more recent pursuit of direct, sovereign access to the Red Sea for landlocked Ethiopia has severely strained the fragile rapprochement. Abiy’s repeated public assertions that Ethiopia possesses an inherent right to maritime access have been interpreted by officials in Asmara as a direct threat to Eritrean sovereignty and an implicit declaration of territorial conflict.
Could the Current Conflict Spread in the Region?
Regional and international experts share a deep concern that the ongoing violence could widen into a multi-state conflagration.
Laura Hammond, a professor in development studies at SOAS University of London, warned that this worst-case scenario is already materializing. She noted that the risks of the conflict spreading to neighboring countries are currently being realized through Eritrea’s active support for the TPLF and the broader opposition alliance. Hammond cautioned that if the fighting persists, there is a strong probability that Eritrea could escalate its involvement by deploying ground troops inside Tigray, alongside the severe risk of further inflaming political and ethnic violence within and concerning Sudan.
Martin Plaut, an expert analyst specializing in the Horn of Africa, echoed these warnings, emphasizing the "real danger" of a wider regional conflagration.
The situation remains exceptionally volatile, Plaut noted, warning that the current political climate is so fragile that it would require only a single minor spark to ignite a full-scale regional war capable of engulfing Ethiopia, Eritrea, and neighboring Sudan.
