Ethiopia, Eritrea ramp up rhetoric: Are they inching towards war?

Ethiopia and Eritrea are trading accusations as fighting intensifies in and around Tigray. Ethiopia says Eritrean forces crossed its border and advanced as far as 60km into Tigray. It calls this a violation of sovereignty and a possible act of aggression. Eritrea denies the incursions and says Ethiopia is preparing an offensive.

The dispute has moved to the UN Security Council. Ethiopia invoked its right to self-defence under Article 51 of the UN Charter. Eritrea urged the council to condemn what it called Ethiopia’s “deplorable declaration of war” and seek deterrent measures. Each government presents the other as the main threat.

The claims remain only partly independently verified. The article says alleged Eritrean involvement and its scale are difficult to substantiate. Still, the confrontation now reaches beyond Tigray, involving Ethiopia’s demand for Red Sea access and Eritrea’s fear for its sovereignty. That combination could widen the conflict across the Horn of Africa.

Tigray is Ethiopia’s northern region and the base of the Tigray People’s Liberation Front, or TPLF. It became the main battleground because the TPLF is part of a rebel alliance fighting Ethiopian government forces. The conflict is also tied to the unresolved relationship between Tigray’s leaders, Addis Ababa and neighbouring Eritrea.

Fighting spread across Tigray when the rebel alliance attacked government forces on September 23. The rebels captured Mekelle, Tigray’s capital, and its airport before announcing a withdrawal on October 3. Government-allied forces then entered the city. Later reports described advances at Idaga Hamus and Abiy-Adi.

Tigray is therefore both a local political battlefield and a place where regional tensions meet. Eritrean troops are alleged to have entered the region, although the article says their involvement is not independently confirmed. Ethiopia’s Red Sea ambitions and Eritrea’s security fears now make developments in Tigray important beyond the region itself.

The article describes the 2020–2022 Tigray war as a devastating, two-year civil war between Ethiopia’s government and Tigray rebels. It does not provide a death toll, displacement figure or total troop strength. That means the war’s human cost cannot be quantified from this source, even though its description makes clear that the conflict was severe.

The current fighting is geographically broad. On September 23, a rebel alliance launched attacks against Ethiopian government forces across Tigray, Amhara and Afar. Rebels captured Mekelle and its airport, then announced their withdrawal on October 3. Government-allied forces subsequently entered the capital.

Battlefield reports also placed government-allied forces in Idaga Hamus and Abiy-Adi. It remained unclear who controlled the towns immediately beforehand and whether Eritrean troops fought there. The article therefore establishes a multi-region conflict, but not its total scale or death toll. It warns that further escalation could destabilise the wider Horn of Africa.

The 2022 peace agreement ended the two-year war between Ethiopia’s government in Addis Ababa and Tigray rebels. It created a pause in the direct civil war and improved the immediate relationship between the federal government and Tigray’s forces. The agreement is therefore the main barrier between political confrontation and renewed large-scale fighting.

That barrier is now under pressure. A rebel alliance including the TPLF attacked government forces across Tigray, Amhara and Afar on September 23. The rebels captured Mekelle before announcing their withdrawal. Government-allied forces then entered the capital and later reported taking Idaga Hamus and Abiy-Adi. The article also describes alleged Eritrean troop movements into Tigray.

Renewed combat threatens to undo the agreement’s stabilising effect. It could restore the cycle of territorial advances, accusations and outside involvement that marked the earlier war. The dispute also now includes Ethiopia’s demand for Red Sea access and Eritrea’s security concerns, making a return to the old conflict potentially broader.

Ethiopia wants access to the Red Sea because it is landlocked and has repeatedly argued that direct sea access is essential. Prime Minister Abiy Ahmed reiterated that position on Monday. The article does not specify the exact economic or military arrangements Ethiopia seeks, but the demand has become a central source of tension with Eritrea.

Eritrea controls the port of Assab and fears Ethiopia may try to take it. That concern connects a dispute over maritime access with Eritrea’s broader anxiety about sovereignty. Eritrea won independence from Ethiopia in 1993, and the neighbours later fought a deadly border war from 1998 to 2000.

The Red Sea issue makes the Tigray fighting more dangerous. What began as accusations about troops and rebels is now tied to borders, ports and national survival. The article says Ethiopia’s access quest and Eritrea’s sovereignty concerns are interconnected with wider regional rivalries, including Egypt’s strategic competition with Ethiopia over the Nile.

A direct war would transform the current crisis from an Ethiopian internal conflict into an interstate confrontation. Ethiopia and Eritrea have already fought a deadly border war, and both now describe the other’s actions as existential threats. Eritrea warns that an Ethiopian offensive would cause huge devastation for people in both countries.

The mechanism for wider escalation is already visible. Ethiopia has invoked self-defence after alleging Eritrean troops entered Tigray. Eritrea denies the incursions and says Ethiopia is preparing an offensive. The dispute is also linked to Ethiopia’s demand for Red Sea access and Eritrea’s fear over Assab. These issues could pull military, political and regional interests into one conflict.

The article says the consequences could extend beyond the two neighbours. The wider Horn of Africa could be destabilised, with repercussions for Sudan, Somalia and Red Sea security. Egypt’s strategic rivalry with Ethiopia over the Nile adds another connected tension. The immediate future depends on whether accusations become sustained interstate military action.

Sovereignty means a country has authority over its territory and political affairs without another state unlawfully intervening. The right of self-defence is the UN Charter principle that allows a state to respond when it suffers an armed attack. Ethiopia invoked Article 51 after alleging Eritrean troops entered Tigray, presenting the alleged incursion as aggression.

The escalation mechanism is political as well as legal. Ethiopia treats an alleged border crossing as a threat to its territory. Eritrea rejects the accusation and instead describes Ethiopia’s position as a declaration of war. If either side acts militarily before the facts are independently established, the other may portray that action as proof of hostile intent.

This can turn a local conflict into an interstate war. Troop movements in Tigray become evidence in competing national narratives. The article stresses that Eritrean involvement and its scale remain difficult to verify independently. Yet both sides increasingly treat the other’s narrative as existential, increasing the risk that disputed claims produce real military escalation.
