African Union Urges Restraint as Ethiopia and Eritrea Sever Diplomatic Ties

Addis Ababa, 1 October 2026
Ethiopia shut its embassy in Asmara and expelled ten Eritrean diplomats, prompting Eritrea to completely sever diplomatic relations amid rising regional tensions.

A Sudden Diplomatic Rupture

The geopolitical landscape of the Horn of Africa has shifted dramatically as the diplomatic relationship between Ethiopia and Eritrea completely collapsed. This sudden breakdown follows months of escalating tension, previously exacerbated by external diplomatic alignments, including maritime access disputes that have strained regional relations [1]. On Thursday, 1 October 2026, the Ethiopian Ministry of Foreign Affairs announced the closure of its embassy in Asmara and ordered ten Eritrean diplomats based in Addis Ababa to leave the country within 48 hours [4]. In a swift retaliatory move, the Eritrean government announced the total severance of all diplomatic relations with Ethiopia [3].

Accusations of Subversion and Territorial Ambitions

According to official statements from Addis Ababa, the decision to expel the Eritrean diplomats was prompted by their involvement in activities that posed a direct threat to Ethiopia’s national security, in violation of the Vienna Convention on Diplomatic Relations [4]. Eritrea’s Ministry of Information quickly dismissed these claims as baseless [3]. Instead, Asmara accused the Ethiopian government of maintaining a hostile campaign for the past three years, using the quest for sovereign Red Sea access as a cover for plans to invade Eritrean ports and sovereign coastlines [3].

Hostilities Reignite in Northern Ethiopia

Further complicating the diplomatic fallout is Eritrea’s accusation that Ethiopia is actively hosting, training, and arming armed opposition groups to instigate regime change in Asmara [3]. These developments mark a complete reversal of the temporary alliance the two nations shared during the Tigray war, a relationship that has deteriorated severely since the signing of the 2022 Pretoria peace agreement [6]. The diplomatic rupture coincides with a dangerous resurgence of domestic conflict; in the week of 21–27 September 2026, Tigrayan forces launched a major offensive in northern Ethiopia, seizing airports before federal forces and allied militias launched counterattacks, eventually recapturing the strategic town of Alamata on Monday, 28 September 2026 [5][6].

A Complex Web of Regional Alliances

The conflict is rapidly drawing in wider regional powers. Ethiopia’s army chief, Field Marshal Birhanu Jula, has formally accused Eritrea, Sudan, and Egypt of providing logistical and political backing to anti-government forces [5][6]. While Egypt formally rejected these allegations on Tuesday, 29 September 2026, asserting a policy of non-interference [5], security analysts warn of an emerging ‘Tsimdo’ alliance [5]. This anti-Ethiopia axis, reportedly driven by Asmara and Cairo, seeks to encircle Addis Ababa and pressure it into accepting Nile water arrangements that favour Egypt’s historical claims [5].

Maritime Security and the Bab el-Mandeb Threat

This African rift is converging with a parallel maritime crisis across the Red Sea. Throughout September 2026, Yemen’s Houthi forces expanded their coastal presence, seizing Mocha and strategic islands near the Bab el-Mandeb strait [5]. Because landlocked Ethiopia relies on neighbouring Djibouti for more than 97% of its trade [5], any disruption in these shipping lanes due to Houthi attacks or regional warfare poses a severe threat to commercial transport and humanitarian supply lines [5][6]. Security analysts warn that a combined blockade of the Bab el-Mandeb strait could have catastrophic economic consequences for the entire region [5].

Dire Implications for Refugees and Host Communities

For the thousands of Ethiopian and Horn of Africa refugees living in Kenya’s Kakuma refugee camp and Kalobeyei integrated settlement, this geopolitical volatility directly threatens their future stability [GPT]. The collapse of diplomatic ties and the outbreak of fresh fighting in northern Ethiopia crush any immediate prospects for safe, voluntary repatriation [GPT]. Furthermore, as regional instability threatens trade corridors and humanitarian shipping lines, there are growing fears that vital aid resources destined for vulnerable refugee and host communities in the Turkana region could face severe delays [5][6][GPT].

African Union Intervenes with Urgent Appeal

In response to the rapidly deteriorating situation, the African Union Commission issued an urgent appeal on Thursday, 1 October 2026, calling for maximum restraint [2]. The Commission urged Ethiopia, Eritrea, and Egypt to refrain from any actions or statements that could further destabilise the region [2]. Emphasising the critical importance of maintaining open channels of communication, the African Union has offered to facilitate diplomatic dialogue to de-escalate tensions and preserve regional peace [2].
