Ethiopia Warns Eritrea It Will Defend Itself After Border Incursion

What changed

Ethiopia has accused Eritrea of an “all-out invasion” of Tigray and warned the UN Security Council that it will defend itself. Ethiopia says Eritrean forces advanced up to 60km into Tigray; reported Ethiopian drone strikes then hit Eritrean forces near Adigrat, 115km north of Mekelle.

Eritrea denies the accusation and says Ethiopia launched an “unprovoked war of aggression.” The confrontation comes two weeks into renewed fighting between Ethiopia’s government and the Tigray People’s Liberation Front (TPLF), after TPLF forces withdrew from Mekelle and Ethiopian forces took control of the city.

Why it matters

This is no longer only a fight between Ethiopia’s government and the TPLF. Ethiopia and Eritrea, former wartime allies, are now trading accusations of invasion and aggression after severing diplomatic ties last week. That turns a fragile internal conflict into a direct interstate confrontation.

The geography matters. Eritrean forces were reportedly inside Tigray, while strikes landed near Adigrat. If those movements and attacks continue, the battlefield could stretch northward from Mekelle and pull Eritrea more openly into Ethiopia’s conflict.

The immediate picture remains unclear: the scale and direction of Eritrean troop movements have not been independently verified, the strikes’ casualties and military effect are unknown, and it is not yet clear whether the confrontation will widen beyond Tigray. Ethiopia’s appeal to the Security Council shows that the dispute has already moved from battlefield claims to an international diplomatic crisis.
