Arresting Ethiopia’s slide back toward War in Tigray

KUALA LUMPUR, 30 SEPTEMBER 2026 —

Ethiopia’s Northern Frontlines: TPLF’s Multi-Pronged Offensive Threatens Regional Spillover as War Looms

The offensive, the first major military operation by the newly formed Alliance for Survival, marks a dramatic escalation in a conflict that risks drawing in Eritrea, Sudan, and Gulf powers, threatening to merge Ethiopia’s internal war with neighboring crises and trigger a humanitarian catastrophe.

The renewed hostilities shatter the fragile 2022 Pretoria peace deal, which ended Ethiopia’s deadliest war of the 21st century—a conflict that killed hundreds of thousands and left deep-seated grievances unresolved. With the TPLF now openly pursuing the overthrow of Prime Minister Abiy Ahmed’s government, Addis Ababa faces a critical juncture: whether to respond with a full-scale ground invasion—risking further devastation—or escalate drone strikes while regional powers maneuver for influence.

The stakes are not just Ethiopian but continental, as the Horn of Africa’s overlapping wars in Sudan, Somalia, and Yemen risk being further destabilized by Ethiopia’s descent into chaos.

A Collapsed Peace and the Birth of a Rebel Alliance

The roots of the current crisis trace back to 2018, when Abiy Ahmed—backed by the Oromia region—rose to power, ending the TPLF’s three-decade dominance over Ethiopia’s federal system. What followed was a two-year war (2020–2022) that began with the TPLF’s surprise attack on federal forces in Tigray, only to see Abiy’s coalition gain the upper hand by 2022.

The Pretoria Agreement, brokered by the African Union (AU) under former Nigerian President Olusegun Obasanjo, was hailed as a breakthrough: the TPLF pledged to disarm, while Tigray would be governed by an interim administration approved by both sides.

Yet the deal was fatally flawed. The TPLF accused the government of imposing a lopsided settlement, while Addis Ababa claimed the rebels failed to disarm. Eritrea, a former ally of the federal government, felt sidelined in the negotiations and resented what it saw as a premature peace that left its anti-TPLF campaign unfinished. Meanwhile, territorial disputes—particularly Amhara’s seizure of western Tigray during the war—remained unresolved, leaving thousands of displaced Tigrayans in limbo.

By April–May 2026, the TPLF reasserted control in Tigray, ousting the interim administration and reinstating Debretsion Gebremichael as regional president. In response, Abiy cut federal funds to Tigray, restricted fuel supplies, and intensified drone strikes—a tactic that escalated in August and September 2026, targeting TPLF military buildups near the Amhara-Tigray border.

The final spark came on September 20, 2026, when the TPLF announced the Alliance for Survival, uniting six rebel groups, most notably the Amhara Fano—a militant movement that has waged insurgency against the federal government since August 2023. The alliance’s stated goal: the overthrow of Abiy’s government.

The Offensive: A Three-Front War with Uncertain Outcomes

The federal government’s response was swift. On September 22, it launched its largest drone campaign since August, striking TPLF positions near Wollo, Amhara, where rebel groups were reportedly massing. By September 23, large-scale ground fighting broke out across three fronts:

1. Amhara-Tigray Border (North Wollo Zone) – The TPLF and Amhara Fano launched a joint assault on federal forces, advancing toward Weldiya and Lalibela, two strategic towns in northern Amhara. The offensive has already displaced civilians and raised fears of a broader insurgency in Amhara.

2. Tigray-Afar Border (Eastern Front) – The TPLF attacked the Tigray Peace Forces, a government-backed militia, while an Afar rebel group joined the fray, fighting alongside the TPLF in two locations along the contested frontier.

3. Seizure of Tigray’s Airports – Without resistance, the TPLF took control of Mekelle International Airport, Axum Airport, and Shire Airport, replacing federal police with its own forces. The federal government cancelled all flights to Tigray, cutting off the region from the outside world.

The Alliance for Survival’s offensive is the first coordinated military action by the rebel coalition, marking a shift from localized insurgencies to a unified campaign. However, analysts and diplomats do not believe the rebels pose an immediate threat to Addis Ababa, though the risk of escalation into a full-scale war remains high.

Who Starts the War? Blame Game and Deflections

Ethiopian officials and diplomats blame the TPLF for the escalation. Getachew Reda, a former senior TPLF official now advising Abiy, accused the rebels of starting a "new war." The U.S. Ambassador to Ethiopia, Ervin Massinga, echoed this in a statement, expressing "disappointment" over the TPLF’s "large-scale offensive."

The TPLF, however, denied responsibility, framing its actions as defensive. In a statement, the group claimed it was responding to the federal government’s "open invasion" on September 22, when drone strikes targeted its forces near Wollo. "Our actions are not aggressive but a reaction to the federal government’s escalation," the statement asserted, without providing further details.

Privately, senior Ethiopian government officials have indicated that Addis Ababa now seeks to "eliminate the TPLF as a threat," though another official suggested the government would prefer to avoid a full-fledged war. Abiy, who has avoided large-scale ground offensives in the past, may now see limited options—especially as the TPLF’s advances threaten to consolidate control over Tigray and potentially draw in Eritrea.

Regional Powder Keg: Eritrea, Sudan, and Gulf Proxy Wars

The risk of regional spillover is acute. Eritrea, once a key ally of Abiy in crushing the TPLF, has quietly realigned with its former enemy, fueled by bitterness over the Pretoria deal. Addis Ababa accuses Asmara of coordinating the rebel alliance, a claim Eritrea has neither confirmed nor denied.

Meanwhile, Sudan’s civil war has become entangled with Ethiopia’s conflict. The federal government alleges that Sudan’s army is hosting thousands of TPLF fighters in disputed border areas, raising fears of cross-border attacks. In retaliation, Ethiopia has allowed arms flows to Sudan’s Rapid Support Forces (RSF), a paramilitary group backed by the United Arab Emirates (UAE)—a close ally of Addis Ababa.

This proxy war dynamic is further complicated by Gulf rivalries: - The UAE, Ethiopia’s key arms supplier, is widely seen as backing the RSF against Sudan’s army, which is aligned with Saudi Arabia, Egypt, and Eritrea—all hostile to Ethiopia. - Egypt, already locked in disputes with Ethiopia over the Grand Ethiopian Renaissance Dam (GERD), has no incentive to stabilize the region.

Diplomats warn that the superheated regional climate—where continental and Gulf powers are lining up on opposing sides—makes diplomatic solutions elusive. The Horn of Africa is already a war zone, with conflicts raging in Somalia, Sudan, and Yemen, and a new Ethiopian war could merge these crises into a single, uncontrollable conflagration.

Humanitarian Time Bomb: Displacement, Destruction, and Mass Casualties

A major federal ground invasion of Tigray—which some officials privately acknowledge as a possibility—would almost certainly lead to: - Extensive destruction of infrastructure, including cities, hospitals, and farmland. - Mass displacement, with hundreds of thousands fleeing as they did in 2020–2022. - Civilian casualties, as indiscriminate airstrikes and ground fighting take their toll.

The humanitarian cost would be catastrophic, particularly given that northern Ethiopia remains fragile after years of war, famine risks, and economic collapse. The UN and aid groups have already warned of a looming crisis, with food shortages and medical supply disruptions worsening as fighting intensifies.

The Diplomatic Race Against Time

With the window for de-escalation narrowing, African and international leaders are scrambling to prevent all-out war. Key figures include: - Olusegun Obasanjo (AU’s Horn of Africa envoy), who mediated the 2022 peace deal but has made little progress in recent shuttle diplomacy. - Kenyan President William Ruto and former President Uhuru Kenyatta, who have historically engaged with both sides. - U.S. Ambassador Ervin Massinga, who has urged restraint but faces limited leverage over Abiy.

- Saudi Arabia, which could pressure its allies (Eritrea, Sudan, Egypt) to avoid further meddling. - The UAE, which must deter Addis Ababa from excessive military escalation to prevent regional destabilization.

The International Crisis Group (ICG) has warned that without urgent diplomacy, the conflict could spiral into a full-blown war, with unpredictable consequences for the Horn of Africa and beyond. The Alliance for Survival’s offensive has shaken the fragile balance, and both sides now face a choice: - The TPLF must halt its advances and return to negotiations.

- Abiy’s government must avoid a ground invasion and engage in emergency talks before the situation escalates beyond control.
