Eritrea and Ethiopia accuse each other of provoking war as Tigray rebels retreat

What happened between Ethiopia, Eritrea, and the Tigray People's Liberation Front (TPLF) that led to accusations of a new war?

The crisis began inside Ethiopia’s northern Tigray state. The Tigray People’s Liberation Front launched attacks against Ethiopian federal forces last month. Ethiopia then accused Eritrea of backing the rebels, while Eritrean troops appeared in northern Tigray. The dispute matters because Ethiopia and Eritrea severed diplomatic ties and exchanged accusations of aggression.

Ethiopian forces pushed back the TPLF and captured Mekelle, Tigray’s capital. Witnesses also reported that the rebels lost Shire and Adigrat. Ethiopia used heavy drone strikes against Eritrean troops, while a security source estimated that 5,000 to 8,000 Eritrean soldiers were in Tigray. The military movement connected the internal rebellion to relations between two neighboring countries.

By Friday, Ethiopia called Eritrea’s conduct an act of aggression and claimed a right to self-defense. Eritrea’s information minister said Ethiopia had launched an unprovoked war. TPLF forces were retreating toward Sheraro, near Eritrea’s border. The fighting therefore threatened to expand beyond Tigray, especially amid Ethiopia’s demands for sea access and Eritrea’s fear of invasion.

What is the Tigray People's Liberation Front, and why is it fighting Ethiopia's federal government?

The Tigray People’s Liberation Front, or TPLF, is the armed rebel organization at the center of the fighting in Ethiopia’s Tigray state. The article describes it as a force with fighters, a local administration, and control of Tigray’s capital before federal troops captured Mekelle. It does not provide a full history of the organization or explain all its political goals.

The immediate reason for the fighting is clear. TPLF forces launched attacks against Ethiopia’s federal forces last month. The federal army responded by advancing through Tigray, taking Mekelle, and pushing the rebels out of Shire and Adigrat. TPLF fighters and administrators left Shire, while rebels retreated toward Sheraro near Eritrea’s border.

The conflict has weakened the TPLF’s position. A regional specialist described the movement as “withering,” with low morale and defections. Eritrean troops were also seen in Tigray, and Ethiopia accused Eritrea of supporting the rebels. The article presents this foreign involvement as a major reason the internal conflict now threatens regional escalation.

How many Eritrean soldiers are estimated to be in Tigray, and how large is that force compared with the local conflict?

The estimated Eritrean presence was substantial: a foreign security source told AFP that between 5,000 and 8,000 Eritrean soldiers were in Tigray. The source spoke anonymously, so the figure is an estimate rather than a confirmed official count. Ethiopia’s foreign minister described Eritrea’s involvement as aggression, while Eritrea rejected that accusation.

The soldiers were not merely reported far from the fighting. Eritrean forces were seen in northern Tigray, including Adigrat, and Ethiopian forces targeted them with heavy drone strikes. The article also says Ethiopian forces pushed back Eritrean troops. These details show direct military involvement alongside the broader conflict between federal forces and the TPLF.

The article does not state the total size of the Ethiopian army, the TPLF, or the forces fighting locally. That means the Eritrean contingent’s exact proportion cannot be calculated from the available facts. Still, thousands of foreign troops made the conflict more than an internal rebellion and increased the risk of a wider Ethiopia-Eritrea confrontation.

What could happen if fighting between Ethiopia and Eritrea expands beyond Tigray into a regional war?

If the fighting expands beyond Tigray, the central danger is a direct war between Ethiopia and Eritrea. The conflict began as an Ethiopian internal struggle involving federal forces and the TPLF. Eritrean troop deployments and Ethiopian drone strikes have connected that struggle to a second country. The two governments have already severed diplomatic relations and exchanged accusations of aggression.

The article gives a concrete mechanism for escalation. Ethiopian forces have targeted Eritrean troops in Tigray, while the TPLF has retreated toward Sheraro, near Eritrea’s border. Ethiopia also insists it has a right to direct sea access. Eritrea interprets that demand as a possible threat to its port at Assab and has linked it to earlier alleged invasion plans.

The immediate result could be continued fighting involving national armies rather than only Ethiopian federal forces and TPLF rebels. The article does not predict a specific outcome or name other countries that might join. It does show that the internal conflict already threatens to become regional, while Eritrean troops and border tensions remain active.

Why have Ethiopia and Eritrea repeatedly become enemies, including during their 1998–2000 border war and the Tigray conflict?

Ethiopia and Eritrea have repeatedly become enemies because their relationship combines unresolved territorial tensions, competing security fears, and disputes over the outcome of war. Eritrea became independent from Ethiopia in 1993. The countries then fought a brutal border war from 1998 to 2000, showing how quickly their rivalry could become military conflict.

Relations improved after Abiy Ahmed came to power in 2018. Eritrea later fought alongside Ethiopia during Ethiopia’s 2020–2022 civil war against the TPLF. That cooperation placed Eritrean troops on the same side as Ethiopia’s federal government. It did not settle the countries’ underlying disagreements or remove their mutual suspicions.

Relations deteriorated after the civil war ended. The article says Eritrea was angry about how the war was concluded and feared an Ethiopian invasion. Ethiopia’s repeated demand for direct sea access has intensified that fear because Eritrea sees possible access to Assab as a threat. The new accusations therefore build on an older pattern of war, cooperation, and renewed mistrust.

Why does Ethiopia want access to the Red Sea, and why does Eritrea see possible access to the port of Assab as a threat?

Ethiopia wants direct access to the sea because it is landlocked. The article says Ethiopia has repeatedly insisted that it has a right to such access, but it does not identify a specific legal agreement or route. The demand matters because it directly touches Eritrea’s coastline and raises questions about control of ports.

Assab is the key example. It is an Eritrean port on the Red Sea, and Eritrea interprets Ethiopia’s demand for access as a threat to invade and seize it. Eritrea’s information minister connected Ethiopia’s “infatuation with the Red Sea” to previous alleged intentions to wage a war of invasion. Thus, a demand presented by Ethiopia as access is understood by Eritrea as a possible security threat.

This disagreement adds a strategic dimension to the Tigray fighting. Eritrea already accuses Ethiopia of launching an unprovoked war, while Ethiopia accuses Eritrea of aggression and claims self-defense. The article does not state what final access arrangement Ethiopia seeks. It shows that the issue deepens mistrust and could make a wider conflict more likely.

What does it mean for a country to claim a right to self-defense or to accuse another country of a 'war of aggression' under international law?

Under widely accepted international-law principles, a state’s right to self-defense concerns using force after an armed attack, subject to necessity and proportionality. A “war of aggression” generally describes unlawful force initiated against another state, rather than force justified as defense. These are legal positions, not automatic facts, and their validity depends on evidence and the circumstances.

In this case, Ethiopia’s foreign minister said Eritrea’s conduct was a blatant act of aggression and invoked Ethiopia’s inherent right to self-defense. Eritrea’s information minister answered that Ethiopia was waging an unprovoked war of aggression. The competing claims reflect opposite descriptions of who started the interstate violence and whether the response was legally justified.

The article does not provide a legal ruling, an independent investigation, or enough detail to determine which claim is correct. It reports Eritrean troops in Tigray, Ethiopian drone strikes, and the diplomatic break. Those facts explain why the legal language matters: each government is presenting its military actions as defensive while portraying the other side as the aggressor.
