Ethiopian troops reach Zalambessa border town, sources say

Ethiopian troops reached Zalambessa on the Eritrean border, six sources said on October 13, as diplomats sought to prevent war.

The reported advance brings federal forces to a border town previously held by Tigrayan rebels, but does not establish who controls it. Whether Eritrean soldiers or rebel fighters remained there was unclear, and a spokesperson representing a militia aligned with the government did not confirm an army takeover.

Zalambessa advance leaves control uncertain

The accounts came from four individuals communicating with residents, a diplomat, and a conflict specialist maintaining contact with the opposing parties. Neither the Ethiopian military nor the office of Prime Minister Abiy Ahmed immediately answered requests for comment.

Witnesses and a conflict monitor said Eritrean soldiers entered Zalambessa during the preceding week to assist the rebels. Eritrea rejects the allegation that its forces crossed into Ethiopian territory, leaving their reported presence contested.

The advance follows a federal counteroffensive that has pushed rebel forces northward out of several towns, according to the supplied accounts. Renewed fighting began in September when an alliance headed by the Tigray People's Liberation Front (TPLF) launched an offensive.

Rival accusations reach Security Council

Ethiopia has accused Eritrea of supporting the insurgents and told members of the UN Security Council that Eritrean forces penetrated as far as 60 kilometers, or 37 miles, beyond the border. That distance is an Ethiopian government claim, not an independently established measure of an incursion.

Eritrean Foreign Minister Osman Saleh has instead sought council measures against Ethiopia. His letter invoked Chapter VII of the UN Charter, a framework permitting responses that can include sanctions or armed intervention; the request itself does not constitute council authorization.

Asmara characterizes Ethiopia's invasion accusations as a "declaration of war" and wants the UN to deter Addis Ababa. The council's Greek presidency said members were scheduled to discuss the Horn of Africa behind closed doors on October 13, with no outcome available in the supplied material.

Sea access complicates renewed confrontation

The opposing positions reverse an earlier partnership. After years of confrontation, the neighbors reached peace in 2018, and Eritrea subsequently backed Ethiopia's federal authorities during the Tigray conflict of 2020–2022.

Access to the sea is another dispute between the governments. Ethiopia lost its coastline when Eritrea became independent in 1993; Addis Ababa describes recovering maritime access as essential to its survival, while maintaining that it seeks a negotiated, peaceful route.

The immediate uncertainty concerns the forces present in Zalambessa, rather than an announced diplomatic settlement. Establishing who holds the town, whether Eritrean units are inside Ethiopia, and whether either government changes its public position would help distinguish a domestic battlefield advance from a direct confrontation between states.

If diplomacy contains the border confrontation, it would still leave the renewed federal-rebel fighting unresolved. If the neighbors instead enter open conflict, the fighting would acquire an interstate dimension in a region already experiencing other wars and tensions around the Red Sea.
