Eritrea and Ethiopia have severed diplomatic ties after Ethiopia closed its embassy in Asmara and expelled 10 Eritrean diplomats, marking a major reversal of the rapprochement that began in 2018.
The diplomatic rupture comes as fighting escalates in northern Ethiopia and as regional governments increase their involvement in disputes over security, maritime access and political influence in the Horn of Africa.

What happened between Eritrea and Ethiopia
On October 1, 2026, Ethiopia announced that it would close its embassy in Asmara and expel 10 Eritrean diplomats, declaring them persona non grata in Addis Ababa.
The Ethiopian government gave the diplomats 48 hours to leave and said their activities posed a direct threat to national security and breached the Vienna Convention on Diplomatic Relations.
Ethiopia did not publicly detail the specific activities attributed to the diplomats, but said the decision responded to what it described as Eritrea’s direct and indirect acts of hostility and belligerence.
The Ethiopian Foreign Ministry also said it continued to value the countries’ historical and people-to-people ties and remained committed to peaceful coexistence and the peaceful resolution of disputes.
Eritrea rejected Ethiopia’s account and responded by severing diplomatic relations.
In a statement issued by its Ministry of Foreign Affairs, Eritrea accused Ethiopia of pursuing an aggressive campaign aimed at obtaining sovereign access to the Red Sea through pressure on Eritrean ports and coastal areas.
Asmara also alleged that Ethiopia had hosted, trained and armed Eritrean opposition groups in an effort to destabilize the Eritrean government, claims Ethiopia has not accepted.
The Eritrean statement said the government had “no option” but to reciprocate after Ethiopia’s diplomatic measures.
Why the diplomatic break matters
The collapse of diplomatic relations reverses the breakthrough reached in July 2018, when Eritrea and Ethiopia declared an end to their state of war and pledged to restore diplomatic, transport, trade and communications links.
That agreement followed two decades of hostility after the 1998–2000 border war, although relations later deteriorated again during the Tigray conflict.
The latest rupture removes formal diplomatic channels at a time when communication between the two governments is especially important.
Embassy closures can make it more difficult to manage border incidents, assist citizens, exchange warnings and pursue direct negotiations, even when governments say they still support peaceful coexistence.
The crisis also carries wider implications because Ethiopia has repeatedly described reliable access to the Red Sea as a strategic and economic priority, while Eritrea regards its ports and coastline as central elements of national sovereignty.
Those competing positions have raised the risk that a dispute over maritime access could become connected to military and political conflicts inside Ethiopia.
Fighting in northern Ethiopia adds pressure
The diplomatic escalation coincides with renewed fighting in northern Ethiopia, where the security situation has deteriorated across multiple fronts.
The United Nations has warned that fighting in the north is disrupting humanitarian operations and has reported that humanitarian personnel were recently forced to travel by road after being unable to leave the Tigray region by air.
The current conflict environment has intensified accusations between Addis Ababa and Asmara.
Ethiopia has accused Eritrea of hostile involvement in its internal security problems, while Eritrea has denied seeking confrontation and has blamed Ethiopia for threatening its sovereignty.
Claims about troop movements and possible Eritrean involvement in the fighting remain contested, and the governments have issued sharply different accounts of events.
That uncertainty makes it difficult to determine whether the diplomatic break will remain primarily political or develop into a broader military confrontation.
Egypt, Sudan and Somalia seek a stronger regional position
On October 4, Eritrean President Isaias Afwerki joined the leaders of Egypt, Sudan and Somalia for a consultative summit in New Alamein, Egypt.
The four governments issued a joint declaration supporting respect for sovereignty, territorial integrity and non-interference in internal affairs.
The declaration also called for peaceful solutions to conflicts and emphasized the security of the Red Sea, the Gulf of Aden and the Bab el-Mandeb Strait.
The summit did not announce a formal military alliance, but it demonstrated that Eritrea’s diplomatic confrontation with Ethiopia is unfolding within a wider regional contest.
Egypt, Sudan, Eritrea and Somalia said they wanted greater cooperation in infrastructure, energy, trade and regional connectivity, while also stressing the importance of national institutions and political stability.
The meeting may also increase pressure on governments outside the region to support de-escalation and prevent the Ethiopia-Eritrea dispute from drawing in additional states.
What happens next
The immediate priority will be whether Ethiopia and Eritrea establish any backchannel for communication after the formal severance of ties.
Without direct diplomatic missions, discussions may have to proceed through neighbouring governments, regional organizations or international institutions.
The African Union could face increased pressure to help prevent border incidents and encourage both sides to keep disputes from becoming military confrontations.
Humanitarian agencies will also be watching developments closely because renewed conflict in northern Ethiopia could restrict access to civilians and complicate the movement of aid workers.
For Eritreans and Ethiopians living abroad, the diplomatic break may affect consular services, document processing and assistance from embassies, although the practical impact will depend on how each government implements the closures.
For now, the most concrete development is diplomatic rather than military: Ethiopia has closed its mission in Asmara, Eritrea has severed relations, and both sides are publicly accusing the other of creating the conditions for escalation.
