Ethiopia’s renewed Tigray conflict, Red Sea ambitions and regional rivalries raise the risk of a wider war across the Horn of Africa.
The war that resumed in Tigray in late September 2026 has fused with Ethiopia's quest for sovereign sea access, Eritrea's fear for Assab and Egypt's Nile dispute, while the humanitarian response runs without a plan.
On the night of October 4, Ethiopian federal forces carried out airstrikes on Adwa and Sheraro, two towns in northern Tigray, killing nine and eight people, respectively, according to a humanitarian bulletin cited in news reports and compiled by the Critical Threats Project (CTP). The next day, in Addis Ababa, the House of Peoples' Representatives opened its new session and reappointed Abiy Ahmed as prime minister. In his address, Abiy again pledged that Ethiopia would obtain direct access to the sea. The day before the strikes, federal troops and a federally backed Tigrayan militia had entered Mekelle, the regional capital, without significant resistance. Two days before that, Eritrea had severed diplomatic relations with Ethiopia, calling Addis Ababa's pursuit of a coastline "a publicly pronounced declaration of war."
Taken one at a time, these look like a counterinsurgency, a constitutional ritual and a diplomatic quarrel. Taken together, they show what changed in the Horn of Africa in 2026. The confrontation between the federal government and the Tigray People's Liberation Front (TPLF) that resumed in late September has fused with two older disputes: Ethiopia's campaign for sovereign access to the Red Sea, which Eritrea reads as a threat to its port of Assab, and Egypt's long quarrel with Ethiopia over the Nile. A struggle over who governs a region of about six million people now carries the risk of an interstate war beside one of the world's busiest maritime corridors.
That convergence also challenges the two labels most often applied to the region. "Tinderbox" implies a fire still waiting for a spark. The spark came around September 23, when Tigrayan forces seized the airports of Mekelle, Axum and Shire, prompting the African Union (AU) Commission chairperson to call for restraint, describe the 2022 peace deal as the "cornerstone" of any settlement and ask the AU's envoy, Olusegun Obasanjo, to engage the parties. The Famine Early Warning Systems Network (FEWS NET) subsequently recorded the spread of fighting into Afar and Amhara. "Forgotten" fares no better. The AU Commission issued a further statement on October 1 and a clarification on October 4; the African Commission on Human and Peoples' Rights weighed in on October 8; the United States and the European Union have publicly urged respect for territorial integrity; and the United Nations (UN) relief chief has demanded safe access. CARE's annual ranking of the ten most under-reported crises of 2025 did not include Ethiopia. The region is watched. What it lacks, as later figures show, is a plan and the money to carry one out.
The war returned largely because the Pretoria Agreement of November 2, 2022, which ended the 2020–2022 conflict, stopped the shooting without settling its causes. An analysis by the German Institute for International and Security Affairs (SWP) published in July identified three unmet obligations. The status of Western Tigray, the Southern Zone and Tselemti, areas held by Amhara forces since the war began and claimed by the Amhara region, was left to a constitutional process that never started. About 750,000 people remained displaced inside Tigray, mostly from those areas. Disarmament, demobilization and reintegration (DDR) efforts also stalled: about 274,000 Tigrayan fighters were registered for the program, but only about 63,000 had passed through it, with progress frozen since 2025.
Political cohesion within Tigray began to unravel. Getachew Reda, the TPLF's chief negotiator at Pretoria and the first head of the interim administration, was expelled from the party in August 2024 and replaced as interim president in March 2025 by Tadesse Werede. The National Election Board of Ethiopia revoked the TPLF's registration in May 2025, so that, in federal law, the signatory to the peace deal no longer existed. In April 2026 Addis Ababa extended the interim administration's mandate; in May the TPLF reinstated the regional parliament elected in 2020, which named party chairman Debretsion Gebremichael as president. Tigray was excluded from the June 1 general election, in which Abiy's Prosperity Party won about 90 percent of the seats. Federal budget transfers to the region had been in arrears since October 2025, leaving teachers unpaid. Meanwhile, the federal army supplied a breakaway militia, the Tigray Peace Force. Getachew, now a federal adviser with ministerial rank, co-founded a council in May that pledged to remove the TPLF "by any means necessary." Neither side was passive. In January, Tigrayan forces crossed into Tselemti and the Southern Zone before pulling back, and in June the regional assembly passed a mobilization law amid reports of forced conscription.
Ethiopia's other fault lines widened the breach. On September 20, the TPLF joined the Amhara Fano National Movement (AFNM), the Oromo Liberation Army and four smaller groups in an alliance aimed at ousting Abiy. The conflicts in Amhara and Oromia have their own origins and grievances, and they should not be read as extensions of Tigray's. The Fano insurgency began in 2023 among Amhara nationalists who once fought alongside federal forces against the TPLF and whose claim to Western Tigray is precisely what Tigrayans want reversed. SWP's description of such partnerships as "a tactical collaboration, not a strategic alliance" fits the record. Even so, tactical cooperation matters on the ground: the AFNM took Wurgessa on October 3 and Mehal Meda on October 7, threatening federal supply lines that run through Amhara into Tigray, according to CTP's October 8 assessment.
Eritrea is where internal war meets interstate risk, and the evidence needs to be read in layers. Since 2023 Abiy has described the Red Sea as Ethiopia's natural boundary; in November 2025 Foreign Minister Gedion Timothewos said Ethiopia had long had grounds to wage war on Eritrea but had refrained. Asmara, which fought alongside federal troops in 2020–2022, has since moved toward the TPLF, and its forces never fully left northeastern Tigray. What is confirmed is the diplomatic rupture: on October 1 Ethiopia expelled ten Eritrean diplomats and announced an embassy closure, and Eritrea cut ties. What is reported is that on October 7 witnesses saw Eritrean troops in Adigrat and Idaga Hamus, and CTP geolocated footage to the area. What is alleged is a senior Ethiopian official's claim that one mechanized and three infantry divisions crossed the border. What is assessed is CTP's judgment that satellite imagery shows no large-scale buildup and that any incursion was probably limited; the Armed Conflict Location and Event Data project (ACLED) reported a withdrawal northward on October 8. Eritrea denies any presence and says Ethiopia is building a pretext to seize Assab. The US Embassy said on October 8 that fighting appeared concentrated north of Adigrat and north of Shire, after warning a day earlier of possible long-range attacks on Ethiopian military installations.
Regional alignments have hardened around this fault without yet resulting in direct intervention. On October 4, Egypt, Eritrea, Somalia and Sudan issued a joint declaration at El Alamein that rejected recognition of Somaliland, declared Red Sea governance "the exclusive responsibility of the littoral states" and restated Egypt's position on the Grand Ethiopian Renaissance Dam. Between December 2025 and July 2026, Cairo signed port and maritime agreements with Djibouti, Eritrea and Somalia, including for Assab and Massawa. Ethiopia's army chief accused Eritrea, Egypt and Sudan of backing the TPLF, an allegation none has confirmed. The bloc is less solid than it looks. Somalia's president met Abiy in Addis Ababa on September 29 and days later offered Ethiopia commercial use of two or three Somali ports under Somali sovereignty. This arrangement reflects the approach outlined in the Turkish-brokered Ankara Declaration of December 2024; Ethiopia's 2024 memorandum with Somaliland remains unimplemented. Sudan's war adds a second channel. SWP cites cargo-flight patterns and satellite imagery suggesting Ethiopia has become a transit route for Emirati supplies to the Rapid Support Forces, while a TPLF-linked unit known as Army 70 fights alongside the Sudanese Armed Forces. SWP warns that this force could operate from the Sudanese border in any conflict over Western Tigray. The United Arab Emirates remains among Abiy's closest financial and military partners, while Saudi Arabia, which once tried to mediate between Addis Ababa and Asmara, is wary of further militarization of the Red Sea.
The drive for sea access is rooted in genuine economic concerns. In the fiscal year that ended in July, Djibouti handled 96.71 percent of Ethiopian cargo moving through maritime gateways, with Berbera at 2.74 percent, according to Ministry of Transport and Logistics (MoTL) data. Dependence on a single road-and-rail corridor is a genuine vulnerability for a country of Ethiopia's size. Yet a coastline would not buy security on its own. The southern Red Sea is itself contested: ACLED reported Houthi gains around Bab al-Mandab on October 1, Yemeni government forces said on October 6 that they had retaken the area, and Lloyd's List Intelligence recorded a Houthi blockade of Saudi oil shipments since July 20. The commercial offers from Somalia and the existing Djibouti route address Ethiopia's trade problem. Only the demand for sovereignty, which no neighbor accepts, turns a logistics question into a casus belli.
Assessing the humanitarian toll requires the same precision in reporting the figures. Much of it predates September. According to the UN High Commissioner for Refugees, as of August 31 Ethiopia had 1,919,993 internally displaced people, most displaced by earlier conflict and disasters, and hosted 1,129,183 refugees and asylum-seekers, including about 484,000 South Sudanese, 365,000 Somalis, 172,000 Eritreans and 98,000 Sudanese. New displacement since late September has not been reliably counted; the UN Office for the Coordination of Humanitarian Affairs (OCHA) reports fresh displacement, fuel shortages and funding limits but no verified totals for Tigray or Amhara, and flights to Tigray's airports remain suspended. FEWS NET places South and East Tigray in Crisis (Integrated Food Security Phase Classification Phase 3) and warns that a delayed harvest will extend the lean season. The International Organization for Migration recorded more than 20,000 journeys from Ethiopia through Djibouti since September 10, most along the eastern route toward Yemen and the Gulf, a path on which migrants face drowning, detention and abuse.
The funding figures reveal the scale of the shortfall. Ethiopia has had no published humanitarian response plan for 2025 or 2026; Sweden's aid agency attributes the delay to unresolved negotiations between aid agencies and the government's disaster commission, which prefers to lead the response itself. Without a plan there is no stated requirement, so the shortfall cannot be expressed as a share. The UN Financial Tracking Service (FTS) records US$653.7 million for Ethiopia so far in 2026, against US$710.6 million for all of 2025. For comparison, the Ukraine plan is 71.9 percent funded, the flash appeal for the occupied Palestinian territory 40.2 percent, Sudan's plan 43.2 percent and Somalia's 31.6 percent. The United States historically supplied nearly two-thirds of Ethiopia's appeal, and the 2025 aid freeze and terminations forced staff cuts and office closures, even though Washington was still the largest donor in December 2025.
Three paths are plausible from here, and the table below sets out the indicators for each. In the first, the federal army holds Mekelle and the main roads, the TPLF retreats into the northeast and the Eritrean border, and Tigray settles into an insurgency administered by a federally appointed interim government; the risk is a long war of airstrikes against towns, with Fano attacks on the supply lines. In the second, a clash on the border or a strike inside Eritrea turns the Tigray campaign into an interstate war, with Assab as the stated or unstated prize and Egypt as Eritrea's diplomatic patron. In the third, battlefield exhaustion, fiscal pressure and AU mediation produce a pause that revives Pretoria's unfinished business. None of these is foreordained, and elements of the first and third can coexist.
Scenario | Trigger | Warning indicators | Constraints |
|---|---|---|---|
A. Contained reconquest, protracted insurgency | Federal forces consolidate Mekelle and main roads; TPLF leadership relocates north. | Continued airstrikes on towns; interim administration named; Fano attacks on Amhara supply routes; aid convoys restricted. | Federal fiscal strain; Fano pressure; TPLF fighters near the Eritrean border. |
B. Ethiopia–Eritrea interstate war | Confirmed Eritrean deployment inside Ethiopia or Ethiopian strikes in Eritrea. | Satellite-verified troop massing; formal declarations at the UN; Assab rhetoric in official statements; Egyptian military cooperation with Asmara. | AU and Gulf pressure; International Monetary Fund and World Bank program risk; no neighbor's support for sovereign access. |
C. AU-mediated pause | Battlefield stalemate plus external leverage. | Direct talks under Obasanjo; restored flights and fuel; resumed demobilization; credible monitoring. | TPLF lacks legal status; no agreed formula for Western Tigray; mutual distrust. |

The first priority is to address Tigray’s internal fault lines before they fuel a wider regional war. That requires a political settlement that confronts the unresolved disputes at the heart of the conflict. The AU Commission, working with the Intergovernmental Authority on Development and the three governments that helped broker Pretoria—the United States, Kenya and South Africa—should convene direct talks that treat the TPLF as a negotiating party, regardless of its registration status, and that place Western Tigray, the return of displaced people and demobilization on one agenda. Progress would be measured by the cessation of airstrikes on populated areas, the reconstitution of an AU monitoring team to issue public reports on a fixed schedule, and the adoption of a dated return plan for the disputed areas.
Yet a settlement within Tigray will remain fragile unless Ethiopia’s confrontation with Eritrea is contained. Preventing the internal conflict from spilling across an international border therefore requires a separate channel for military de-escalation. The AU Peace and Security Council, supported by the UN Secretary-General's office and by Saudi Arabia and Turkey, which have mediated in the region before, should press Addis Ababa and Asmara for a military hotline and third-party verification of the border. The test is simple: an independent finding, whether by satellite review or monitors, that no Eritrean forces are inside Ethiopia and no Ethiopian forces are massed opposite Assab, together with a public Ethiopian commitment that sea access will be pursued only by agreement.
Containing the military threat, however, will not by itself alleviate the suffering of civilians caught in the conflict. A parallel humanitarian response is needed, beginning with OCHA and Ethiopia’s Disaster Risk Management Commission (EDRMC) agreeing on a response plan or flash appeal within weeks, giving donors a defined funding requirement and allowing the FTS to report coverage against it. Its markers are a published plan, resumed humanitarian flights to Mekelle, Shire and Axum, and fuel deliveries into Tigray. European members of the boards of the International Monetary Fund (IMF) and the World Bank should make clear that humanitarian access and civilian protection affect the risks facing Ethiopia’s programs. Formal program reviews should explicitly address these concerns.
Beyond containing the conflict and addressing its humanitarian consequences, a durable settlement must confront the economic grievance that links Tigray’s war to Ethiopia’s wider regional ambitions: dependence on external routes to the sea. Ethiopia’s MoTL and the Somali government should therefore convert the Ankara Declaration into a signed commercial port-access agreement, while renegotiating Djibouti’s terms in parallel. Progress should be measured by the ministry's annual cargo statistics, specifically a rising share of Ethiopian trade moving through alternative routes under commercial agreements rather than territorial threats. The airstrikes on Adwa and the pledge in Addis Ababa belong to the same geopolitical story: peace in Tigray now runs through the question of the sea, and the question of the sea runs through Tigray.
