Three years after the catastrophic conflict in Ethiopia’s northern Tigray region — a war that claimed hundreds of thousands of lives and displaced millions — the fragile peace that followed is rapidly fraying. Renewed confrontations between the Ethiopian federal army and Tigrayan forces, shifting regional alliances, and long-standing strategic ambitions over access to the Red Sea have combined to create a powder-keg situation, with echoes of some of the region’s bloodiest decades.
The Tigray war, which raged from 2020 to 2022, erupted after Prime Minister Abiy Ahmed dissolved the coalition that had previously governed Ethiopia and marginalised the Tigray People’s Liberation Front (TPLF), which had long controlled the northern region. Federal forces, allied militias, and Eritrean troops faced off against the TPLF in a brutal conflict that engulfed the region. The war left a devastating toll: estimates suggest hundreds of thousands of deaths, while sexual violence, massacres, and mass displacement devastated communities.
The peace deal that followed in late 2022, brokered under international auspices, formally ended hostilities, but the accord left critical issues unresolved. Questions of disarmament, justice, political inclusion, and control over regional institutions were only partially addressed. Those unresolved fissures have resurfaced with alarming force, threatening to destabilise not just Tigray but the broader Horn of Africa.
New Hostilities Rise in Northern Ethiopia
Tensions reignited in late January 2026, when the Ethiopian federal army launched drone strikes on Tigrayan positions. Troop movements and artillery deployments along key approaches to the region signalled that the government in Addis Ababa was preparing for more than isolated skirmishes. In tandem, flights to Tigray were temporarily suspended, and foreign journalists attempting to access the region were detained, raising fears that the conflict could escalate while the world watches from a distance.
The Ethiopian government has publicly accused Eritrea of supporting armed groups operating in Tigray and of violating Ethiopian sovereignty by positioning troops near the border. In response, Addis Ababa demanded the immediate withdrawal of Eritrean forces. Eritrea, however, rejected these claims, framing them as diplomatic aggression. What makes the current crisis particularly volatile is that it reflects not just a resurgence of domestic conflict between Addis Ababa and Tigrayan authorities but also a dramatic reversal of regional alliances. Eritrea, which had fought alongside Ethiopian federal forces during the 2020–22 war, is reportedly exploring ties with certain Tigrayan factions — a development that shocks analysts and underscores the fragility of post-war relationships in the Horn.
The roots of Ethiopia–Eritrea hostility stretch back decades. Eritrea, annexed by Emperor Haile Selassie in 1960 after Italian colonial rule, endured severe repression under successive Ethiopian regimes. A protracted independence struggle finally secured Eritrean sovereignty in 1993, but relations with Addis Ababa remained tense, erupting into a brutal border war from 1998 to 2000 that claimed tens of thousands of lives. Even after the 2018 peace agreement between Eritrean President Isaias Afwerki and Prime Minister Abiy Ahmed, which formally normalised diplomatic ties and earned Abiy the Nobel Peace Prize, mutual distrust persisted.
The eruption of civil war in Tigray in 2020 saw Eritrean troops again deployed alongside Ethiopian federal forces against the TPLF, reinforcing patterns of militarised intervention in regional disputes. Today, Ethiopia’s leadership continues to pursue a long-standing strategic imperative: access to a seaport on the Red Sea. Ethiopia remains Africa’s most populous landlocked nation, reliant on Djibouti for most of its imports and exports. The lack of direct maritime access constrains trade and economic development, a limitation Addis Ababa is keen to address, even as it risks reigniting conflict with Eritrea.
Red Sea access has become a central strategic concern. The port of Assab, controlled by Eritrea, offers the most direct route for Ethiopia’s imports and exports to global markets. While the Ethiopian government does not officially demand direct control over the port, officials have increasingly framed current arrangements as economically and politically untenable, signalling a willingness to assert influence by other means. For Eritrea, whose economy remains fragile and whose government is wary of regional dominance by its powerful neighbour, Ethiopia’s posture is interpreted as a potential threat, prompting defensive military and diplomatic posturing.
The delicate balance between economic ambition and territorial sovereignty is central to understanding why the current tensions are so acute. Any misstep by either side could ignite a full-scale confrontation, especially given that both governments have mobilised forces near the border. Military analysts warn that this is not merely a question of domestic unrest but a potential interstate crisis that could draw in multiple regional actors.
Humanitarian Consequences
For civilians in Tigray, the prospect of renewed conflict is terrifying. During the 2020–22 war, residents endured starvation, indiscriminate violence, and systematic human rights abuses. Today, food insecurity remains acute, while infrastructure, health systems, and social cohesion are fragile. Renewed fighting would likely trigger mass displacement, disrupt aid delivery, and deepen the humanitarian crisis. Humanitarian organisations are already sounding the alarm, warning that the conditions for another disaster are in place.
The Horn of Africa crisis cannot be understood in isolation. Eritrea and Ethiopia have both supported different factions in Sudan’s ongoing conflict, and Gulf states, including the UAE, Qatar, and Saudi Arabia, exert influence through funding, political backing, and diplomatic channels. These overlapping interests mean that a flare-up in Tigray or along the Eritrean border could have cascading effects across the region, drawing in actors far beyond Addis Ababa and Asmara.
The geopolitical stakes are high. The Red Sea is a vital maritime artery for international trade, connecting the Mediterranean to the Indian Ocean. Any instability that threatens free navigation or regional security could have global economic implications, particularly for energy markets. Moreover, a protracted conflict risks reversing the modest economic growth and regional cooperation achieved in the Horn over the past decade.
A History of Unresolved Grievances
To grasp the current crisis, one must understand the historical grievances shaping both Ethiopia and Eritrea’s behaviour. Eritrea’s annexation and subsequent struggle for independence left deep scars, fostering a national narrative centred on sovereignty and defence against perceived Ethiopian aggression. For Ethiopia, the Tigray war and subsequent regional instability reflect the challenges of governing a highly diverse federal state, balancing ethnic autonomy with central authority, and ensuring economic development for a population of more than 120 million.
These grievances are compounded by political calculations. In Tigray, the TPLF maintains a degree of local legitimacy, and federal attempts to assert control without reconciliation risk igniting further rebellion. In Eritrea, the government fears renewed Ethiopian dominance and seeks to maintain leverage in the region. For both governments, domestic political imperatives are intertwined with regional ambitions, creating a dangerous feedback loop.
In recent weeks, the rhetoric from both sides has hardened. Ethiopian officials have warned that any foreign support for Tigrayan factions constitutes a violation of sovereignty, while Eritrean leaders have emphasised their commitment to defending national interests. The concentration of artillery and troop movements along sensitive border areas suggests that both governments are bracing for the possibility of large-scale hostilities.
Analysts note that while neither Addis Ababa nor Asmara has formally declared war, the combination of historical mistrust, ongoing military posturing, and shifting alliances makes the risk of escalation far higher than it has been in recent years. Observers caution that even a relatively minor incident could spiral into full-scale conflict if mismanaged.
International actors, including the United Nations, African Union, and major Western powers, have called for restraint and the immediate resumption of political dialogue. Diplomatic efforts focus on ensuring compliance with the 2022 peace accord and preventing violations of international law. However, the challenge is immense. Past mediation efforts have been hampered by mutual suspicion, limited trust, and rapidly changing local conditions. With each side entrenched in its position, the window for preventative diplomacy is narrowing.
Lessons from History
The Horn of Africa is no stranger to cycles of conflict and uneasy peace. From the Eritrean struggle for independence to the border wars of the 1990s, patterns of mistrust, intervention, and unfinished reconciliation have repeatedly led to renewed hostilities. Today, these historical patterns intersect with modern challenges: a landlocked Ethiopia seeking strategic access to the sea, Eritrea seeking security guarantees, and a Tigray population wary of both federal and foreign military presence.
The stakes extend beyond national borders. Renewed conflict in Tigray or along the Eritrean frontier could destabilise the wider region, exacerbating refugee flows into Sudan and Djibouti, disrupting trade routes, and straining international humanitarian resources. It could also embolden extremist groups, further undermining security in the Horn.
The Human Dimension
Amid these geopolitical calculations, ordinary citizens remain the most vulnerable. In Tigray, families face the daily reality of scarce food, limited medical care, and the constant threat of violence. In Eritrea, economic hardship and political repression limit citizens’ capacity to influence government decisions. Across Ethiopia, communities fear that renewed conflict could reignite ethnic tensions and collapse fragile local governance structures.
The human cost of escalation is difficult to overstate. Every day of military preparation, every troop deployment, and every inflammatory public statement increases the risk that civilians will once again bear the brunt of political and military failure.
Despite the gravity of the situation, there remain avenues for de-escalation. Transparent dialogue, adherence to existing agreements, and international diplomatic engagement can still prevent the crisis from becoming a full-scale war. The challenge lies in the willingness of all actors to compromise and in the capacity of mediators to enforce accountability for violations.
Yet the warning signs are unmistakable. Troop buildups, hardened rhetoric, unresolved political disputes, and shifting alliances combine to create one of the most dangerous flashpoints in Africa today. The fragile peace of 2022 is under threat, and with it, the lives of millions in Tigray and the stability of the wider Horn of Africa.
For Ethiopians, Eritreans, and the international community, the coming weeks may determine whether diplomacy prevails or whether the Horn is drawn once again into the cycle of war, displacement, and humanitarian catastrophe that has haunted it for decades.
The world is watching. The question now is whether history will repeat itself, or whether restraint, dialogue, and international pressure can hold the region from the edge of disaster.
