Tigray Explained, the Region and Ethiopia’s New War in 2026

AFRICA · ETHIOPIA · TIGRAY · GUIDE

Tigray, the mountainous region at the northern tip of Ethiopia, is at war again. Since August 2026, fighting between Ethiopia’s federal government and the Tigray People’s Liberation Front has spread from border skirmishes to drone strikes, airport seizures and, on 3 October, the federal capture of the regional capital, Mekelle.

For an American reader the stakes reach well beyond one region. Ethiopia is Africa’s second most populous country after Nigeria and hosts the headquarters of the African Union. Its quarrel with Eritrea, Egypt and Sudan now runs along the Red Sea shipping route.

This guide explains what Tigray is, how the peace of 2022 broke down, who is fighting whom, and what to watch. For the national picture, see our Ethiopia explainer and our profile of Abiy Ahmed.

Where Tigray Is and Why It Matters

Tigray is one of Ethiopia’s regional states, the federal units that each run their own government under the national constitution. It borders Eritrea to the north and Sudan to the west, with the Ethiopian regions of Amhara to the south and Afar to the east. Mekelle is its capital and largest city.

It is also the cradle of Ethiopian history. Aksum, in central Tigray, was the heart of an ancient kingdom whose obelisks, royal tombs and churches date from the 1st to the 13th centuries AD. UNESCO listed it as a World Heritage site in 1980.

Tigray’s position is what makes its wars regional. Its northern edge faces Eritrea, which fought on Ethiopia’s side in the last war. Its western edge, around Humera, runs along Sudan. Ethiopia itself has been landlocked since Eritrea became independent in 1993, and its leaders say they want a route back to the sea.

The 2020 to 2022 War and the Pretoria Deal

The TPLF, a party born in the 1970s as a rebel movement, was the dominant force in Ethiopia’s ruling coalition until Abiy took office in April 2018. Its relations with him collapsed, and in November 2020 war broke out between the federal government and the TPLF. Eritrea fought on the federal side.

The war killed hundreds of thousands of people. It ended with the Agreement for Lasting Peace through a Permanent Cessation of Hostilities, signed in Pretoria, South Africa, on 2 November 2022 between the government of Ethiopia and the TPLF under African Union auspices.

The deal stopped the fighting but left the hardest questions open. The TPLF wants the return of territories such as Wolkait, Humera and Raya, which are contested with the neighbouring Amhara region, and accuses the federal government of blocking it. The return of displaced people and the disarmament of Tigrayan forces were never completed.

Two Governments in Mekelle

Under the Pretoria deal, Tigray was run by a Tigray Interim Administration whose president is appointed by the federal government. Getachew Reda led it until April 2025, when Abiy appointed Lt. Gen. Tadesse Werede, a former commander of Tigray’s forces.

The TPLF itself was struck off Ethiopia’s register of political parties in 2025. In April 2026 the federal government extended the interim administration’s mandate by a year, which the TPLF rejected.

On Tuesday 5 May 2026, the TPLF reinstated the regional council elected before the war, which made its chairman, Debretsion Gebremichael, head of a parallel regional government. On Friday 8 May his cabinet met in the interim administration’s cabinet hall in Mekelle under armed protection. Tadesse called it an illegal act and warned that those “attempting to seize the administration’s power by force” would be responsible for what followed.

The Reporter, an Addis Ababa newspaper, wrote that the TPLF and a Tigrayan faction known as Tsimdo were “alleged to be working closely with Asmara,” the Eritrean capital. Eritrea has repeatedly denied supporting Ethiopian armed groups.

How the New War Started

Clashes between Tigrayan and federal forces broke out in western Tigray in August 2026, according to Addis Standard, an Ethiopian news outlet. It also recorded drone strikes on a secondary school in Merewa, in southern Tigray, on 10 August and on teachers’ housing in Mekelle on 20 August. A hospital official in Mekelle said at least 13 people were wounded in that strike, five of them children.

On 21 September the TPLF formed an alliance with six other armed groups from across Ethiopia, with the declared aim of removing Abiy’s government. In the Amhara region, Tigrayan forces have fought alongside Fano, an ethnic Amhara militia that rebelled against the federal government in 2023.

Two days later, Tigray’s TPLF-led government said its forces had “entered a defensive war.” They took Mekelle’s airport from federal police overnight on 22 to 23 September, along with the airports of Axum and Shire, and detained federal personnel. Ethiopian Airlines halted its flights to all three cities “due to the current situation in Tigray region.”

The African Union Commission chairperson, Mahmoud Ali Youssouf, said that same day that the airport seizures were “inconsistent with the commitments and obligations within the Pretoria Agreement,” reported fighting in southern Tigray and the Afar region, and called on Ethiopia’s neighbours to refrain from actions that could escalate the conflict.

The Federal Counteroffensive and the Fall of Mekelle

Addis Ababa blamed outside powers. Abiy’s spokeswoman, Billene Seyoum, said members of the rebel alliance had worked together with financial backing from Eritrea. On 27 September, the army chief, Field Marshal Birhanu Jula, accused Eritrea, Sudan and Egypt of supporting the rebels. Sudan and Egypt have rejected the charge, and Eritrea has repeatedly denied backing Ethiopian armed groups.

On Thursday 1 October, Ethiopia closed its embassy in Asmara over what it called Eritrea’s “direct and indirect acts of hostility and belligerence” and expelled 10 Eritrean diplomats. Eritrea cut all diplomatic ties in response. Ethiopia also expelled an Egyptian diplomat, and Egypt expelled an Ethiopian one.

On the ground, federal troops pushed north. On Saturday 3 October, the Tigray Peace Forces, a Tigrayan militia fighting on the government side, entered central Mekelle, followed by the Ethiopian army. The TPLF said its leadership had “temporarily moved out of Mekelle” and would operate from elsewhere. By 6 October markets had reopened in the city, while drone strikes continued elsewhere in Tigray. On 4 October, the state Ethiopian News Agency reported that a new interim administration would be set up in Tigray, with regional elections within a few months; it did not say who would lead it.

Abiy was sworn in for a new five-year term on Monday 5 October, after his Prosperity Party won 438 seats in the House of Peoples’ Representatives in the 1 June election, far more than the 274 needed to form a government. Tigray did not vote. In his first speech of the new term he pledged to “work relentlessly to ensure that the country has access to the sea.”

Who Is Who

Abiy Ahmed, Ethiopia’s prime minister since 2018 and leader of the ruling Prosperity Party, won the 2019 Nobel Peace Prize, in particular for his “decisive initiative to resolve the border conflict with neighbouring Eritrea.” He now accuses Eritrea of arming his enemies.

Debretsion Gebremichael chairs the TPLF and heads the parallel regional government it set up in May 2026. The federal government does not recognise it.

Lt. Gen. Tadesse Werede, a former commander of Tigray’s forces, was appointed interim president by Abiy in April 2025 and opposed the TPLF’s takeover, which pushed him out of office. Kulu Media, an Ethiopian news site, reported on 25 September that he had been detained with other veteran commanders who doubted the new war.

Field Marshal Birhanu Jula is chief of staff of the Ethiopian National Defense Force, the federal army.

Isaias Afwerki has ruled Eritrea since independence in 1993. On 4 October he joined the leaders of Egypt, Sudan and Somalia at a summit in New Alamein, Egypt, that declared the Red Sea the business of coastal states only.

Fano is a loose network of ethnic Amhara militias in revolt against the federal government since 2023, whose fighters now fight alongside Tigrayan forces in Amhara.

What Prediction Markets Say

Polymarket, a crypto-based prediction market, runs bets on the wider crisis. At 1:08 a.m. ET on Wednesday 7 October 2026, “Yes” on Eritrea invading Ethiopia by 31 December was quoted at about 27 cents, a 27% implied chance, up 8 points in a week, with about US$42,800 traded. The same bet with a 31 October deadline stood near 10 cents.

A separate bet on Abiy Ahmed leaving office as prime minister during 2026 stood at about 7.5 cents, with about US$12,600 traded. Both markets are thin by US standards, so a single large order can move them.

Why we show this: prediction markets turn real-money bets into a live probability that moves within minutes of the news, which is why investors, campaigns and newsrooms in the United States now follow them closely. We show them next to polls and official results, never instead of them.

What It Means for You

Travel. The State Department’s Ethiopia advisory of 27 August 2026 puts the country as a whole at Level 3, Reconsider Travel, and tells Americans not to travel to Tigray, Amhara, most of Oromia, or the areas along Ethiopia’s borders with Eritrea, Sudan, South Sudan, Somalia and Kenya. It also warns that exit bans can stop travelers from leaving and that dual US-Ethiopian citizens who entered on Ethiopian passports have been heavily fined.

Flights. Ethiopian Airlines, the state-owned carrier based in Addis Ababa, halted flights to Mekelle, Axum and Shire on 23 September. The suspension covered those three cities in Tigray. Check with the airline before booking any domestic connection in the north.

Investors. A wider war involving Eritrea would sit on the Red Sea, between the Suez Canal and the Gulf of Aden. Abiy’s renewed demand for sea access and the Egypt-led bloc’s insistence that only coastal states govern the Red Sea point in opposite directions.

Families and aid. Communications and banking in Tigray are unreliable. Mekelle residents told Africanews on 6 October that a lack of cash was their main problem after markets reopened.

What Is Not Known

No verified count of deaths or displaced people for the fighting since August 2026 has been published by the UN or the Ethiopian government. Independent access to Tigray, Afar and Amhara is limited.

It is not known where the TPLF leadership and its fighters have regrouped since leaving Mekelle, or how much of Tigray each side holds. Ethiopia’s charges that Eritrea, Egypt and Sudan are helping the rebels have not been backed with public evidence, and all three reject them. It is also not known who will lead the new interim administration Addis Ababa has announced, or where Tadesse Werede is being held.

It is also unclear when Ethiopian Airlines will resume flights to Tigray, and whether the African Union can bring both sides back to talks under the Pretoria framework, as its chairperson has urged.

Frequently Asked Questions

Is Tigray safe to visit in 2026?

No. The US State Department rates Tigray Level 4, Do Not Travel, and Ethiopian Airlines halted flights to Mekelle, Axum and Shire on 23 September 2026 after Tigrayan forces seized the airports.

Who controls Mekelle now?

Federal forces and an allied Tigrayan militia entered Mekelle on Saturday 3 October 2026 after the TPLF said it had temporarily moved out of the city.

What is the Pretoria Agreement?

It is the African Union-brokered deal signed in Pretoria on 2 November 2022 between Ethiopia’s government and the TPLF that ended the 2020 to 2022 war. The African Union still calls it the cornerstone of peace in Ethiopia.

Who leads Tigray?

No one fully. TPLF chairman Debretsion Gebremichael has headed a parallel government since May 2026, but federal forces took Mekelle on 3 October 2026 and Addis Ababa says it will set up a new interim administration. The interim president it appointed in 2025, Lt. Gen. Tadesse Werede, was pushed out by the TPLF.

Why does Eritrea matter to the Tigray conflict?

Eritrea borders Tigray and fought on the federal side in the last war. Ethiopia now accuses it of backing the rebels, which Eritrea denies, and the two countries cut diplomatic ties on 1 October 2026.
