Eritrea severed all diplomatic relations with Ethiopia on Thursday after Addis Ababa closed its embassy in Asmara and ordered 10 Eritrean diplomats to leave within 48 hours, turning a deteriorating security crisis in northern Ethiopia into a formal rupture between two neighboring governments that were military partners only four years ago.
The break followed a day of competing accusations and unexplained blasts in the Ethiopian capital. Reuters reported that three diplomatic sources confirmed hearing explosions in Addis Ababa. A source associated with an opposition alliance claimed drone strikes had targeted sites including the military headquarters, but Reuters said it could not independently confirm that account. The Associated Press reported three blasts at different locations and emphasized that it remained unclear whether they reflected an attack or military training. No independently verified casualty or damage assessment was available.
Diplomatic channels close
Ethiopia's Foreign Ministry said Eritrea had engaged in direct and indirect hostility and activities threatening national security. A statement carried by the state-run Ethiopian News Agency said the 10 diplomats were declared persona non grata and that the embassy in Asmara would close. The government nevertheless said it valued historical and people-to-people ties with Eritrea and remained committed to peaceful dispute resolution.
Asmara rejected Ethiopia's allegations and answered with a total diplomatic break. In its official response, Eritrea's Foreign Ministry accused Ethiopia of years of hostility linked to demands for sovereign access to the Red Sea and alleged support for Eritrean opposition groups. It said expelling Eritrean diplomats left it no option but to reciprocate and sever ties. Those claims are part of each government's case against the other and have not been independently established.
The rupture matters beyond normal diplomatic retaliation. Embassies provide channels for crisis messages, citizen assistance and de-escalation when military movements are easily misread. Their closure removes those safeguards precisely as armed conflict expands across Ethiopia's north and accusations draw in neighboring states.
A domestic war gains a regional dimension
Fighting resumed last week between federal forces and an opposition coalition led by the Tigray People's Liberation Front, or TPLF. Ethiopia has accused Eritrea, Sudan and Egypt of backing that alliance; all three governments deny the allegation. Reuters reported that Ethiopia also expelled an Egyptian diplomat and that Cairo responded by ordering an Ethiopian embassy counselor to leave.
The African Union Commission responded Thursday by urging Ethiopia, Eritrea and Egypt to exercise maximum restraint, preserve communication channels and settle their differences through diplomacy. The statement offered AU support for de-escalation. Its focus on three governments underscored how quickly the renewed Ethiopian conflict has acquired a wider regional dimension.
Eritrea and Ethiopia fought together against the TPLF during Ethiopia's 2020-2022 civil war. Their forces had reconciled after a 2018 rapprochement restored relations following two decades of hostility. But Eritrea was not a party to the November 2022 peace accord between Ethiopia's federal government and the TPLF, and relations between Addis Ababa and Asmara later deteriorated. Disputes over Ethiopia's access to the Red Sea and allegations of cross-border military involvement sharpened the mistrust.
The 2022 agreement was designed to end fighting, restore public services and allow humanitarian access. Those goals are now under direct pressure. On September 23, the United Nations said hostilities had intensified in and around Tigray and spread to neighboring areas after opposition forces seized airports at Mekelle, Axum and Shire. The U.N. called for civilian protection, unhindered aid access and a return to talks under the Pretoria agreement.
What is known — and what remains uncertain
The basic diplomatic sequence is confirmed by both governments: Ethiopia closed its embassy and expelled 10 diplomats; Eritrea then cut ties. The occurrence of blasts in Addis Ababa is also corroborated by Reuters and AP. The cause, targets and effects of those explosions remain unresolved, however. Claims of opposition drone strikes should therefore be treated as allegations unless physical evidence or an official investigation establishes what happened.
Independent reporting from the battle zones is also constrained. Communications have been disrupted, flights suspended and access limited in parts of Tigray, Afar and Amhara. Reuters reported that tens of thousands of people had fled fighting in Afar, while AP described fear among about 16,000 displaced residents at the Hitsats camp in Tigray and interruptions to banking, communications and fuel supplies in Mekelle. Those accounts show the immediate civilian consequences even before the full territorial picture can be verified.
The most consequential question is whether the diplomatic rupture stays political or becomes a precursor to direct interstate conflict. Indicators will include verified cross-border deployments, further expulsions, evidence about the Addis Ababa blasts and whether the AU can restore working contacts among the governments. A return to the Pretoria framework would require not only a halt in the renewed fighting but also credible arrangements for humanitarian access and security guarantees among actors that no longer trust one another.
For now, the closure of embassies is a warning that the crisis has moved beyond a localized contest in northern Ethiopia. Without direct channels and with several governments exchanging allegations, the risk is not simply another phase of Ethiopia's internal war. It is a broader Horn of Africa confrontation in which a tactical incident or unverified claim could trigger decisions that are much harder to reverse.
