Renewed Fighting in Ethiopia Raises Regional Risk as Tigray Conflict Tests Horn of Africa Stability

ADDIS ABABA, Ethiopia, October 2 — Renewed fighting in northern Ethiopia is raising concerns that a new confrontation involving Tigrayan forces could extend beyond the country's borders as competing alliances across the Horn of Africa intersect with conflicts in Sudan and growing strategic competition around the Red Sea.

The latest clashes involve Ethiopian federal forces and a rebel alliance led by Tigrayan forces, reviving memories of the 2020-2022 conflict that caused extensive casualties and displacement.

The regional environment, however, has changed significantly. Ethiopia and neighbouring Eritrea, which were aligned during the previous war, now find themselves on opposing sides. Ethiopia has accused Eritrea of supporting the rebel alliance, an allegation Asmara denies.

The dispute is intertwined with Ethiopia's long-running effort to secure reliable access to the sea. Eritrea's independence in 1993 left Ethiopia landlocked, while relations between the two countries have remained shaped by their 1998-2000 war and subsequent disagreements.

The conflict is also connected to instability in Sudan, where a prolonged struggle between the military and the Rapid Support Forces has drawn in regional and Gulf powers. Ethiopia and Eritrea have been accused of supporting different actors in Sudan, although the countries involved have denied several of the allegations.

Egypt and Sudan are separately at odds with Ethiopia over the country's Grand Ethiopian Renaissance Dam, which they say could affect access to Nile water. Ethiopia has rejected concerns over the project's implications for downstream states.

Further south, Somalia's security challenges and foreign involvement around Somaliland and Puntland add another layer to the regional competition. The UAE has developed significant economic and security relationships in the Horn, while Saudi Arabia has pursued its own strategic relationships south of the Red Sea.

The overlap between these disputes means that developments in northern Ethiopia could affect calculations across several neighbouring states. Maritime security is another concern, particularly as instability around the Red Sea intersects with wider Middle Eastern conflicts.

For governments and international organisations, the immediate challenge is preventing renewed Ethiopian fighting from becoming connected to existing regional conflicts.

The trajectory of the Tigray confrontation will therefore be closely watched not only for its domestic consequences but also for its potential impact on regional alliances, trade routes and security across northeastern Africa.
