What We Know About Ethiopia's Drone Strikes on Eritrean Troops in Tigray

Witnesses in the Tigray region watched military vehicles cross Eritrea's southern border on Wednesday and push roughly 25 miles south to the town of Adigrat, according to civilian accounts, a militia commander and the conflict monitoring group Acled, as reported by The Guardian. By Wednesday evening, those same troops were under fire from Ethiopian government drones, Acled told the Guardian, and the strikes continued into Thursday morning.

The incursion and the response to it have raised the possibility that an internal Ethiopian conflict, barely two weeks old, could widen into a war between Ethiopia and Eritrea, two countries that fought a brutal border war from 1998 to 2000 and share a fraught history dating back decades.

What triggered the fighting in Tigray?

The Tigray People's Liberation Front, the party that dominated Ethiopian politics for nearly three decades before losing power in 2018, launched an offensive against the federal government on September 23, according to the Guardian's reporting. Over the following two weeks, the TPLF and six other armed groups fought Ethiopian government forces across Tigray and the neighboring Amhara and Afar regions.

Ethiopia's military pushed back, and an allied militia known as the Tigray Peace Force took control of Tigray's regional capital, Mekelle, on October 4 after TPLF fighters withdrew from the city, the Guardian reported. Photographs from Mekelle this week show members of Ethiopia's federal police patrolling the city and republican guards stationed at the Mekelle Alula Aba Nega international airport.

Why would Eritrean troops cross into Ethiopia now?

Eritrea has a long history of hostility toward the TPLF, whose forces it battled during the 1998–2000 border war and again during Ethiopia's 2020–2022 Tigray war, when Eritrean troops fought alongside the Ethiopian government against the TPLF. But according to the Guardian, that old enmity has been overtaken by a newer calculation in Asmara: a desire to head off what Eritrean officials perceive as a risk that Ethiopia could move to seize access to the Red Sea, a goal landlocked Ethiopia's leadership has spoken of publicly in recent years.

That shift helps explain why Eritrean forces would move into Tigray even though the TPLF remains, on paper, an old adversary. The troop movement toward Adigrat put Eritrean forces roughly 40 kilometers inside Ethiopian territory, within range of the drone strikes Ethiopia's government launched in response.

What have Ethiopia and Eritrea said publicly?

Neither government has directly confirmed the drone strikes or the circumstances surrounding them, and their public statements have stopped short of acknowledging specifics on the ground.

Eritrea's information minister, Yemane Ghebremeskel, did not explicitly confirm or deny that Eritrean troops were present in Ethiopia. "We are not in the business of refuting wild allegations or narratives," he said in a statement carried by the Guardian.

Ethiopia's foreign ministry, in a statement issued Monday, framed its posture in defensive terms without naming Eritrea directly: "Ethiopia stands ready to defend its sovereignty, territorial integrity, and core national interests, while urging all regional actors to address shared challenges through constru[ctive dialogue]," according to the excerpt published by the Guardian.

How serious is the risk of a wider regional war?

The Guardian's reporting frames the stakes starkly: a government attack on Eritrean troops "raises the risk that renewed internal conflict in Ethiopia could trigger an all-out regional war between the neighbouring countries." The two nations fought one of Africa's deadliest border wars at the turn of the century, and Eritrean forces' more recent alliance with Addis Ababa during the 2020–2022 Tigray war means the current alignment — Eritrean troops moving into Ethiopian territory while Ethiopian drones strike them — marks a reversal from that earlier cooperation.

With seven armed groups now fighting Ethiopia's government across three regions, and a neighboring state's troops already inside Ethiopian borders, the conflict's trajectory depends on decisions neither government has yet made public. Acled, the monitoring group tracking strikes and troop movements on the ground, has not indicated whether the drone campaign has expanded beyond the Adigrat area. For now, the fighting remains concentrated in Tigray's eastern corridor, but the ingredients present — a weakened TPLF, an anxious Eritrea, and a federal government fighting on multiple fronts — are the same ones that produced the region's last major war.
