Ethiopia’s Tigray War Is Breaking Out Again

For nearly four years, the Tigray conflict had remained one of the defining examples of how difficult it is to turn a military ceasefire into a durable political settlement.

Now, the peace is under severe pressure.

Fighting erupted across northern Ethiopia this week as forces aligned with the Tigray People’s Liberation Front, or TPLF, seized control of three airports in Tigray and clashes spread into neighbouring areas. The escalation has effectively brought the unresolved tensions surrounding the 2020-2022 war back to the centre of African geopolitics. Reuters reported that Tigrayan forces seized airports in Mekelle, Axum and Shire while fighting was also reported in Afar and other locations.

The development is particularly significant because it comes less than four years after the Pretoria Agreement ended the previous war.

The African Union has called that agreement the cornerstone of Ethiopia’s peace process and warned that the latest developments risk reversing years of work toward ending the violence. The European Union has likewise called for immediate de-escalation and a return to dialogue.

The central question now is not simply whether fighting will continue.

It is whether Ethiopia is heading toward another prolonged conflict in the north.

What Happened in Tigray?

The latest escalation began with competing accusations from the Ethiopian federal government and Tigrayan authorities.

Ethiopian officials said Tigrayan forces had launched a major offensive against government positions in Afar and Amhara. Tigrayan authorities, however, said their forces were responding to what they described as an attack by federal forces, accusing the government of using aircraft, drones and artillery against Tigray. Those competing accounts mean that the precise sequence of events remains disputed.

What is not disputed is that fighting has resumed and that Tigrayan forces have taken control of three airports.

The African Union specifically confirmed concern over the seizure and occupation of the airports at Mekelle, Axum and Shire, along with the detention of federal personnel and disruption to civilian air services.

Ethiopian Airlines suspended flights to the three airports following the escalation.

That is more than a disruption to commercial aviation.

Airports are strategic infrastructure during a conflict because they can provide access to transportation, logistics and communications networks. Their capture also demonstrates that the latest confrontation has moved beyond isolated clashes.

The conflict is once again becoming territorial.

Why the 2022 Peace Agreement Matters

To understand why the current fighting is so significant, it is necessary to look back at the agreement that ended the previous Tigray war.

The conflict began in 2020 after relations between Ethiopia’s federal government and the Tigray regional authorities deteriorated dramatically. What followed was a devastating war involving Ethiopian federal forces, Tigrayan forces and Eritrean troops, along with other regional actors.

The war lasted two years.

The Pretoria Agreement, signed in November 2022 under African Union mediation, established a permanent cessation of hostilities and created a framework for restoring peace and political stability. The agreement became the central diplomatic mechanism for preventing a return to full-scale war.

But a peace agreement does not automatically resolve every dispute that caused a war.

Questions involving territorial control, political representation, security arrangements, displaced populations and relations between the federal government and regional authorities remained deeply sensitive.

The current fighting demonstrates how fragile that settlement has been.

The African Union has explicitly said that the Pretoria Agreement remains the foundation for sustainable peace and called for direct talks within its framework.

The Conflict Is Already Moving Beyond Tigray

One of the most important aspects of the current crisis is geography.

The fighting is not confined to Tigray.

Reports indicate clashes in neighbouring Afar, while Amhara is also involved in the broader escalation. Reuters reported that Tigrayan forces launched attacks into Afar and Amhara as the conflict intensified.

This matters because Ethiopia is a federal state containing regions with their own political and security structures, and tensions between the central government and different regional actors have been building for years.

Earlier this week, seven Ethiopian armed groups announced an alliance called the Ethiopian Peoples’ Forces Alliance for Survival. The coalition includes groups from several regions, including the TPLF and Amhara Fano forces, although the groups have different political interests and longstanding disputes of their own.

That creates a complicated strategic environment.

The Tigray conflict cannot necessarily be viewed as a simple two-sided confrontation between Addis Ababa and Tigray.

The wider political landscape contains multiple armed groups, regional grievances and competing territorial interests.

If the fighting expands, the number of actors involved could make negotiations considerably more difficult.

Eritrea Is Part of the Bigger Strategic Picture

Ethiopia’s northern conflict also has implications beyond Ethiopia’s borders.

Eritrea shares a long border with Tigray and played a major role during the previous Ethiopian war. Eritrean forces fought alongside Ethiopian federal forces during the 2020-2022 conflict.

Relations between Ethiopia and Eritrea subsequently became tense again.

The Ethiopian government has accused Eritrea of supporting armed opponents, while Eritrea has rejected such allegations. Reuters has reported that the latest Ethiopian opposition alliance includes groups with different regional bases and that Addis Ababa has again raised concerns about external support.

This is one reason the renewed Tigray fighting is being watched closely throughout the Horn of Africa.

Any substantial expansion of the conflict could affect Ethiopia’s relationship with Eritrea, regional security calculations and the wider Red Sea environment.

That does not mean a broader regional war is inevitable.

It means the geographic consequences of renewed fighting could extend beyond the immediate battlefield.

Why the Horn of Africa Cannot Ignore This

The Horn of Africa is already one of the world’s most strategically sensitive regions.

Ethiopia is Africa’s second-most populous country and one of the largest states in the Horn. Its stability affects neighbouring countries, trade routes, migration patterns and regional security.

The country also sits close to the Red Sea and the Bab el-Mandeb, one of the world’s most important maritime corridors.

At the same time, neighbouring Sudan remains engulfed in conflict, while Somalia continues to face militant violence and political tensions.

A prolonged Ethiopian conflict would therefore emerge in an already fragile regional environment.

The concern is not simply that Ethiopia could experience another civil war.

It is that instability in one of Africa’s largest countries could interact with existing crises across the Horn.

That is why the African Union has reacted so quickly.

The AU has asked neighbouring countries to avoid actions that could contribute to escalation and has requested former Nigerian president Olusegun Obasanjo, its High Representative for the Horn of Africa, to support renewed diplomatic efforts.

The International Response Is Already Growing

The international response has developed rapidly.

The European Union said it was deeply concerned about the deterioration in northern Ethiopia and called for an immediate return to the Permanent Cessation of Hostilities Agreement. It also highlighted concerns about civilian protection and humanitarian access.

The United Kingdom issued a statement on September 24 condemning attacks attributed to Tigray Defence Forces, the takeover of the airports and further escalation. London called for an immediate end to hostilities and a return to African Union-led mediation.

The UK also warned that renewed conflict could have severe consequences for civilians, particularly women and girls, while stressing the need for humanitarian access.

These statements are significant because they show that the international focus has already shifted from monitoring tensions to preventing a broader war.

The diplomatic priority is therefore clear: stop the escalation before the battlefield becomes significantly harder to control.

Why the Airports Matter

The seizure of Mekelle, Axum and Shire airports is one of the most visible signs of how rapidly the situation has changed.

Mekelle is Tigray’s regional capital.

Axum is one of Ethiopia’s most historically significant cities.

Shire is an important urban centre in the western part of Tigray.

The three airports collectively connect important parts of the region to the rest of Ethiopia.

Their seizure also forced Ethiopian Airlines to suspend services to the region, disrupting civilian travel.

The airports therefore have both civilian and strategic importance.

Their capture also demonstrates that Tigrayan forces retain significant organizational and military capabilities despite the 2022 peace agreement.

For the federal government, allowing territorial infrastructure to remain outside its control could create significant political and security challenges.

For Tigrayan authorities, controlling these locations provides leverage but also increases the risk of further military confrontation.

The Humanitarian Question Is Already Emerging

The greatest consequences of renewed conflict will not be measured in territory.

They will be measured in human lives.

The previous Tigray war produced enormous civilian suffering, displacement and humanitarian needs. The African Union has warned that the latest escalation threatens to reverse the gains made since the guns fell silent.

The EU has specifically warned about the protection of civilians and humanitarian operations.

The United Kingdom has similarly called for safe and unhindered humanitarian access.

This becomes particularly important if fighting spreads into populated areas or blocks transportation routes.

Tigray already carries the legacy of the previous war.

A renewed conflict could therefore create new displacement while humanitarian organizations are still dealing with the consequences of the earlier crisis.

The longer the fighting continues, the harder it becomes to separate military objectives from civilian survival.

Could This Become Another Full-Scale War?

Tigrayan officials have described the current situation as a full-blown war, while the Ethiopian government and Tigrayan authorities accuse each other of initiating the latest fighting. AFP reported on September 24 that Tigrayan rebels described themselves as being in a state of full-blown war with the federal government, with heavy artillery attacks reported in neighbouring regions.

But it is important to distinguish between a rapidly escalating conflict and a confirmed return to the scale of the 2020-2022 war.

The situation is still developing.

What can be established is that the 2022 peace framework is under severe strain, military activity has expanded beyond Tigray and major infrastructure has been seized.

Whether this develops into a prolonged war depends on several factors.

The first is whether the federal government and Tigrayan leadership can establish a channel for direct negotiations.

The second is whether the African Union can restore the diplomatic framework that helped end the previous conflict.

The third is whether neighbouring states remain outside the fighting.

The fourth is whether other Ethiopian armed groups become actively involved.

Each of these factors could significantly alter the trajectory of the crisis.

The Bigger Political Problem Inside Ethiopia

The latest escalation also exposes a deeper problem inside Ethiopia.

The country’s political conflicts are not limited to Tigray.

Ethiopia has experienced armed insurgencies and political tensions in several regions, including Oromia and Amhara. The formation of the new Alliance for Survival demonstrates that opposition to the federal government is increasingly being expressed through multiple regional movements, although those groups do not necessarily share the same long-term objectives.

This creates a difficult environment for Prime Minister Abiy Ahmed’s government.

The federal government must simultaneously maintain national security, manage regional political disputes and prevent the country from becoming fragmented along ethnic and regional lines.

At the same time, regional authorities argue for greater autonomy and security guarantees.

The underlying dispute is therefore not simply military.

It is constitutional, political and territorial.

That is what makes the latest fighting particularly important.

Even if a ceasefire is restored quickly, the political disputes that produced the escalation will remain.

The Diplomatic Window May Be the Most Important One

The immediate diplomatic opportunity is the Pretoria framework.

The African Union has explicitly called for the parties to return to direct talks under the 2022 agreement.

That is significant because the agreement already provides a diplomatic reference point.

The problem is that the parties must first stop the military escalation sufficiently to make negotiations possible.

Every additional day of fighting can make that harder.

Military victories can change negotiating positions.

Civilian displacement can create new grievances.

New armed groups can enter the conflict.

External actors can become involved.

The longer these dynamics continue, the more complicated the original dispute becomes.

This is why the response from the AU, EU and UK has focused heavily on immediate de-escalation rather than attempting to settle every underlying political dispute at once.

The first objective is to prevent the situation from becoming irreversible.

Ethiopia Has Reached Another Dangerous Moment

The renewed Tigray fighting is not simply another African conflict appearing on the international news cycle.

It is a direct test of whether the peace architecture created after the 2020-2022 war can survive renewed military pressure.

Three airports have been seized.

Fighting has spread beyond Tigray.

Civilian flights have been suspended.

International governments are calling for restraint.

And the African Union is attempting to bring the parties back toward negotiations.

The facts on the ground remain fluid, and the competing accounts from the Ethiopian government and Tigrayan authorities mean that some details of how the latest fighting began remain disputed.

But one fact is already clear.

The peace achieved in 2022 is facing its most serious challenge in years.

For Ethiopia, the immediate priority is preventing the current clashes from developing into another prolonged war.

For the Horn of Africa, the stakes are wider.

The region cannot easily absorb another major conflict.

And for the international community, the question now is whether diplomacy can move faster than the fighting.
