Fresh clashes in northern Ethiopia and rising tensions between Ethiopia and Eritrea are raising concerns about a wider conflict in the Horn of Africa, with analysts warning that regional instability could spill across borders.

While fighting remains localized, accusations of foreign interference and an escalating standoff between Addis Ababa and Asmara are reviving long-standing geopolitical rivalries in the region.

Ethiopia has accused external actors of supporting local anti-government forces. Eritrea, Sudan and Egypt have rejected the allegations, arguing that Addis Ababa is using claims of foreign interference to deflect attention from its domestic political challenges.

Analysts say the growing friction between Ethiopia and Eritrea could have consequences far beyond Tigray.

Regional escalation

Taylor Magnus, Deputy Director for the Horn of Africa Project at the International Crisis Group, says the situation in Tigray may not necessarily develop into another full-scale war, but tensions between Ethiopia and Eritrea are worsening the broader regional outlook.

“So I think, you know, you can see some reasons to believe the war might not be as bad within Tigray, but the fact that Ethiopia and Eritrea are coming up against each other now suggests the regional picture is looking worse and you could see a kind of more broader escalation that goes beyond Tigray which would be a worst case scenario.”

Sudan is considered particularly vulnerable to any spillover. The country is already devastated by a civil war and shares a long, porous border with northern Ethiopia.

Further deterioration could turn eastern Sudan into a corridor for displaced civilians and armed groups, placing additional pressure on a country already struggling with a major humanitarian crisis.

The economic consequences could also extend beyond the immediate conflict zones. Disruptions to trade routes and shipping along the Red Sea could affect regional commerce and exacerbate existing economic pressures.

Regional diplomatic efforts are continuing, with the African Union urging restraint and dialogue to prevent tensions from developing into a wider security and economic crisis.

Humanitarian concerns

The most immediate concern, however, is the humanitarian impact of renewed fighting.

Dr. Hassan Khannenje, Director of the Horn International Institute for Strategic Studies, said allegations of support for armed actors could draw Sudan deeper into the conflict.

“There have been accusations and allegations of support of Ethiopia against Sudan and I think what that does is that it does not exactly support the kind of effort that are meant to help the humanitarian situation in Sudan because it draws Sudan into the conflict theatre in Ethiopia in ways that can lead to tit for tat.”

Ethiopia's 2020-2022 conflict demonstrated how quickly fighting can disrupt civilian life. Transport corridors were blocked, power infrastructure was damaged and banking services were suspended, severely restricting access to essential goods and services.

Humanitarian agencies warn that even limited fighting could disrupt supply lines, push up food prices across borders and leave hundreds of thousands of displaced and resettled families struggling to plant crops or access emergency medical care.

Both the Ethiopian government and international observers recognize that a direct interstate confrontation would carry serious consequences for the region.

With humanitarian operations already facing significant funding and logistical pressures, analysts warn that a miscalculation along the volatile Ethiopia-Eritrea border could turn localized instability into a broader regional crisis.
