Diplomatic relations between Ethiopia and Eritrea have collapsed following a series of rapid escalations that ended the 2018 peace rapprochement between the neighboring states. On October 1, 2026, Ethiopia closed its embassy in Asmara and expelled 10 Eritrean diplomats, a move that prompted Eritrea to respond by formally severing all bilateral diplomatic ties.
The diplomatic rupture occurs as the Ethiopian federal government faces a significant domestic military challenge from a newly formed alliance known as the Ethiopian Peoples’ Forces Coalition for Survival. Comprising the Tigray People’s Liberation Front (TPLF) and the Amhara Fano militia—formerly rival groups—the coalition launched a large-scale offensive on September 23, 2026, across the Tigray, Afar, and Amhara regions.
Rebel forces have successfully seized strategic infrastructure in the northern territories, including the airports in Mekelle, Aksum, and Shire during the final week of September. In response to the loss of territory and the deteriorating security situation, Ethiopian Airlines suspended all flights to Eritrea effective September 30, as well as service to several airports in the northern conflict zones.
Capital Unrest and Drone Strikes
The conflict reached the capital on the night of October 1, 2026. Residents in Addis Ababa reported hearing multiple explosions, while opposition-linked sources claimed responsibility for suspected drone strikes targeting military and national intelligence headquarters. While Ethiopian federal authorities have not officially confirmed the strikes, the reports coincide with the heightened state of alert following the expulsion of foreign diplomats.
The collapse of the 2022 Pretoria peace agreement, which had previously ended the two-year Tigray War, appears finalized by this multi-front offensive. The inclusion of Fano and TPLF forces in a unified command represents a major shift in the internal security landscape, as the federal government struggles to maintain control over the northern highlands and the capital’s immediate periphery.
Broadening Regional Crisis
The breakdown in relations with Asmara is part of a wider diplomatic crisis involving Ethiopia’s neighbors. Simultaneously with the expulsion of Eritrean officials, Ethiopia expelled Egyptian diplomat Ahmed Moharam Ahmed Soliman on October 1. The move follows months of escalating tension over regional security and water rights.
Observers of the Horn of Africa note that the 2018 peace era, which earned Ethiopian Prime Minister Abiy Ahmed a Nobel Peace Prize, has effectively been replaced by a state of total regional instability. With Eritrea now officially hostile and a domestic coalition advancing in the north, the Ethiopian federal government is facing its most significant existential threat since the beginning of the decade.
