Why Renewed Tigray War Risks Regional Conflict

Fighting has erupted across northern Ethiopia as federal troops clash with a formidable rebel alliance led by Tigrayan forces.

On the surface, the renewed violence mirrors the devastating 2020–2022 civil war that claimed hundreds of thousands of lives.

Yet beneath the surface, this latest flare-up threatens to ignite a far more complex regional powder keg.

The strategic backdrop across the Horn of Africa has fractured into an intricate web of proxy rivalries, shifting border alliances, and competing geopolitical ambitions stretching from central Africa to the Middle East.

Unlike the previous conflict, former allies Ethiopia and Eritrea now stand on opposite sides of the battlefield. During the last war, Eritrean President Isaias Afwerki deployed troops to assist Ethiopian Prime Minister Abiy Ahmed against Tigrayan fighters.

Today, Addis Ababa accuses Eritrea of supplying and housing the newly formed rebel alliance—a charge Asmara denies, even after severing diplomatic ties and closing its embassy.

Valuable Access

Crucially, Eritrea now grants Tigrayan forces valuable access to the Red Sea coastline and international supply lines, shattering the complete isolation they faced during previous combat operations.

The root of this diplomatic fallout rests on decades of deep-seated distrust and Ethiopia’s relentless drive to secure direct access to the sea, which it lost when Eritrea gained independence in 1993.

Tensions have spilt over into neighbouring Sudan, where a devastating three-year civil war between the Sudanese military and the paramilitary Rapid Support Forces (RSF) has triggered a massive humanitarian catastrophe.

Ethiopian military leaders accuse Sudan and Egypt of funding Eritrean-backed rebel operations inside Ethiopian territory.

Bitter Dispute

In turn, both Cairo and Khartoum—already locked in a bitter dispute with Ethiopia over the construction of its massive Grand Ethiopian Renaissance Dam—deny any direct interference.

Compounding these regional rivalries is an escalating struggle for dominance between Middle Eastern powers.

The United Arab Emirates has transformed itself into a dominant broker in the Horn of Africa, deploying multi-billion-dollar investments, strategic diplomacy, and discreet military assistance to support the Ethiopian government.

To secure Red Sea access for its landlocked ally, the UAE signed major maritime infrastructure agreements with Somalia’s breakaway region of Somaliland and the semi-autonomous area of Puntland.

National Security

Israel, another strategic partner of Addis Ababa, recognised Somaliland’s independence and actively trains local defence units.

However, Abu Dhabi’s expanding footprint has alarmed Saudi Arabia.

Fearing that Emirati influence along the Red Sea corridor compromises its own national security, Riyadh has forged a counter-alliance broadly aligning with Sudan’s military leadership, Egypt, and Eritrea.

Furthermore, escalating warfare in Iran and maritime strikes by Yemen’s Houthi rebels directly across the Red Sea have heightened global anxieties over commercial shipping lanes.

As regional actors line up along competing fault lines, diplomats warn that the localised clashes in northern Ethiopia no longer represent an isolated domestic crisis.

With proxy interests overlapping across several borders, any further military escalation threatens to drag the entire Horn of Africa into a prolonged and devastating multi-front conflict.
