Eritrea Asks UN Security Council to Act Against Ethiopia's 'Declaration of War' Over Tigray

Eritrea has formally requested that the United Nations Security Council take punitive action against Ethiopia, accusing its neighbor of declaring war and demanding that the international body intervene to halt the escalating confrontation over the Tigray region.

In a letter delivered to the Security Council on Saturday, Eritrean Foreign Minister Osman Saleh asked the 15-member body to "forcefully condemn Ethiopia's deplorable declaration of war against Eritrea" and to adopt what he described as "requisite deterrent measures." The appeal marked a sharp escalation in a diplomatic duel between the two Horn of Africa nations, both of which have spent the past several days trading accusations at the world's most powerful diplomatic forum.

Saleh invoked Chapter VII of the UN Charter in his request, a provision that empowers the Security Council to authorize measures ranging from economic sanctions to military action when it determines that international peace and security are threatened. The Eritrean government's decision to cite that chapter signals that Asmara views the situation as grave enough to warrant coercive international intervention, not merely mediation or statements of concern.

The Eritrean letter came just one day after Ethiopia sent its own communication to the Security Council, claiming that Eritrean troops had launched an "all-out invasion" and had pushed as far as 60 kilometers (37 miles) inside Ethiopian territory in the northern Tigray region. Addis Ababa's foreign minister, Gedion Timothewos, characterized the alleged incursion as "a blatant act of aggression" and said it triggered Ethiopia's inherent right to self-defense under Article 51 of the UN Charter, though he did not detail what military or diplomatic steps his government intended to take in response.

Saleh dismissed Ethiopia's account as "deceitful attempts to rationalise its brazen acts of war," calling the Ethiopian claims "hollow in substance." He warned that the path Ethiopia has chosen would inflict "huge devastation to the peoples of both countries and destabilise the whole region," a reference to the wider Horn of Africa, which has a long history of cross-border conflicts and fragile security arrangements.

The competing letters reflect a dramatic reversal of fortunes in a relationship that had appeared to be improving only a few years ago. Eritrea won independence from Ethiopia in 1993 following a decades-long armed struggle, but the two countries fought a devastating border war between 1998 and 2000 that left tens of thousands dead. Diplomatic ties were restored after Ethiopian Prime Minister Abiy Ahmed took office in 2018, earning him a Nobel Peace Prize, but relations have deteriorated sharply in recent years as disputes over sovereignty, territory, and access to the sea have resurfaced.

At the center of the current crisis is the Tigray region, where an alliance of seven armed groups launched coordinated attacks against federal Ethiopian forces last month. The coalition's stated aim is to overthrow Abiy's government. Ethiopia has accused Asmara of backing the rebel Tigray People's Liberation Front, or TPLF, which fought a brutal war against Ethiopian government forces from 2020 to 2022 — a conflict in which Eritrean troops fought alongside the Ethiopian military. That wartime alliance has since collapsed, leaving the two neighbors on opposing sides of the current fighting.

The Ethiopian army has claimed recent battlefield successes, saying it pushed TPLF fighters back and seized control of Mekelle, the regional capital of Tigray. Ethiopia has also said it carried out drone strikes against Eritrean troops operating inside the region, an acknowledgment that foreign forces are now directly engaged in the conflict. Eritrea has not explicitly confirmed or denied that its soldiers crossed the border, though Eritrean Information Minister Yemane Gebremeskel accused Ethiopia on Friday of pursuing aggression against Eritrea through its demands for sovereign access to the Red Sea.

That demand has become a central fault line. Landlocked Ethiopia has repeatedly insisted that it has a legitimate right to direct access to the sea, an argument Abiy reiterated as recently as Monday. Eritrea interprets those claims as a pretext for an invasion aimed at seizing its port at Assab, which would give Ethiopia a strategic foothold on the Red Sea coast. The issue taps into deep historical grievances on both sides and has been cited by Eritrean officials as evidence of Ethiopia's expansionist intentions.

Faisal Roble, a specialist on the Horn of Africa, told Al Jazeera from Nairobi that both governments appear to be positioning themselves for a full-scale confrontation. "There is really no doubt that both of them are inching towards an open conflict," Roble said. He added that the letters to the Security Council amount largely to diplomatic theater, describing them as "posturing and making sure that they have some sort of international support on their side." In his assessment, neither capital expects the Council to resolve the dispute, but both hope to win the battle for international legitimacy before fighting intensifies further.

The Security Council now faces a difficult choice. Any formal action would require agreement among its permanent members, several of whom have strategic interests in the Horn of Africa and have historically been reluctant to intervene in the region's internal conflicts. A statement of condemnation, let alone sanctions or military measures, could be blocked or diluted during negotiations. In the meantime, the absence of a robust international response may only encourage both sides to press ahead with military preparations.

Regional powers are watching the standoff with growing alarm. A full-scale war between Ethiopia and Eritrea would be the first direct state-on-state conflict between them since the 1998-2000 border war, and it would unfold in a region already strained by the Tigray conflict, instability in Sudan, and the presence of multiple armed factions across porous borders. Humanitarian agencies warn that renewed fighting could displace large numbers of civilians and disrupt aid routes that serve millions of people dependent on assistance.

For Eritrea, the appeal to the United Nations represents an attempt to internationalize the crisis and cast Ethiopia as the aggressor before the fighting widens. For Ethiopia, the letter to the Council serves to justify any military response as an exercise of self-defense under international law. With both sides dug in and diplomatic channels narrowing, the coming days may determine whether the standoff remains a war of words or becomes a war in fact — a prospect that Roble and other analysts say is growing more likely by the day.
