TLF ANALYSIS | Ethiopia’s Red Sea Obsession and Eritrea’s Tigray Gamble: Is the Horn of Africa Heading Towards a Regional War?
The Horn of Africa is heading toward a dangerous paradox. Ethiopia wants access to the sea because it believes its future depends on it. Eritrea fears losing its coastline because it believes its survival depends on keeping it. Caught between these two convictions is Tigray, a region that has barely begun to recover from its last devastating war.
By the Editorial Team of TLF
In the past 72 hours, the confrontation has entered a more worrying phase. Reports of Eritrean involvement in renewed fighting inside Ethiopia have multiplied. Ethiopian forces and their allies now control several important Tigrayan towns. Unverified reports of Ethiopian military movements toward the Eritrean port of Assab raise a more dangerous possibility: that the fight over Tigray could become a direct war between two sovereign states.
The danger is not only another Ethiopian-Eritrean clash. It is the link between Ethiopia's domestic fractures, Eritrea's security calculations, Egypt's rivalry with Addis Ababa, the war in Sudan, and the competing interests of Gulf powers along the Red Sea.
The Horn of Africa already has the ingredients for a regional war. The open question is whether its governments can keep those ingredients from igniting.
TLF Assessment: The risk of a wider regional conflict is now substantial. A prolonged proxy confrontation is plausible. Direct Ethiopia-Eritrea hostilities have become a credible path to escalation. A broader regional war is possible but not inevitable. Three factors will decide the outcome: military movements around Assab, the scale of Eritrea's role in Tigray, and whether external powers restrain their partners or push them further.
The Last 72 Hours: A War Spreading in Several Directions
The conflict can no longer be read through a single battlefield.
On 11 October, the Armed Conflict Location & Event Data Project (ACLED) recorded Ethiopian National Defense Forces and their ally, the Tigray Peace Force, taking Adwa in central Tigray. ACLED's updates also described Eritrean troops setting up defensive positions in the mountains near the road to Zalambessa, after Ethiopian and allied forces retook Adigrat.
Control of towns does not mean control of the countryside. The Tigray People's Liberation Front (TPLF) still has armed units and can keep fighting outside the major cities.
On 12 October, The New Humanitarian published an investigation by Daniel Berhane. Drawing on local sources, it reported Eritrean forces taking part in clashes at several sites, including Adi Hageray, about 60 kilometres from Shire in northwestern Tigray.
That location matters. Earlier accounts placed Eritrean movements in eastern Tigray, around Adigrat and Zalambessa. Reports from farther west point to a wider military footprint. The scale and chain of command remain hard to confirm independently.
The most explosive claim concerns a different front.
On 12 October, UMD Media reported that Ethiopian forces crossed into Eritrea on 11 October after fighting near Bure and took Daba Sima, a locality on the approaches to Assab. The outlet said it could not verify the advance, the claimed Eritrean withdrawal, or the casualty figures. Treat these claims as unconfirmed.
They still warrant close watching. If confirmed, an Ethiopian push toward Assab would mean the maritime dispute had moved from rhetoric to territorial fighting.
Another development points the other way. Associated Press reported on 12 October that government-aligned forces have retaken Mekelle and that commercial flights to the Tigrayan capital have resumed. A government adviser promised visible improvements.
A reopened airport does not mean peace. A capital can be under government control while the surrounding region stays militarised, divided and open to renewed fighting.
Assab: The Port That Could Change Everything
At the centre of the confrontation is a port that has become far more than an economic objective.
Assab sits on Eritrea's Red Sea coast, close to Ethiopia's Afar region. Before Eritrean independence in 1993, Ethiopia had direct access to the sea. Its later reliance on foreign ports, particularly Djibouti, has become a lasting strategic concern.
For a country with Ethiopia's population, economic ambitions and geography, reliable maritime access is a legitimate development priority.
But negotiating access to a port is different from asserting a right to control another country's territory.
Prime Minister Abiy Ahmed has repeatedly described maritime access as a national necessity. Eritrea hears in this rhetoric a threat to its sovereignty, especially when Assab is mentioned.
Reuters reported on 9 October that Ethiopia accused Eritrea of a major incursion and invoked its right to self-defence. Eritrea rejected the allegations and said Addis Ababa was building a pretext for aggression.
On 10 October, Reuters reported Eritrea's appeal to the UN Security Council for action to deter Ethiopia.
Both governments now frame their positions in the language of existential security. That is dangerous. When a government concludes that its survival requires a military response, compromise starts to look like surrender.
Ethiopia does not need to own a coastline to secure commercially viable access to the sea. Eritrea does not need to accept Ethiopian territorial claims to join a mutually beneficial port arrangement. The problem is that an economic question is increasingly being turned into a matter of national survival.
Eritrea and Tigray: Former Enemies, Current Partners of Convenience
The most striking shift concerns Eritrea's relationship with the TPLF.
During Ethiopia's 2020–2022 civil war, Eritrean forces fought alongside the federal government against the TPLF. The war devastated Tigray and left serious allegations of atrocities, displacement and mass suffering.
Now reports suggest Asmara has moved closer to elements of the movement it once tried to destroy.
This is not evidence of reconciliation. It is a strategic realignment against a shared adversary: Abiy Ahmed's government.
In an assessment published by ACLED, East Africa analyst Dr Jalale Getachew Birru offers two possible explanations for Eritrea's conduct. The first is Asmara's dissatisfaction with the 2022 Pretoria peace agreement. The second is its opposition to Ethiopia's pursuit of Assab and its apparent wish to keep Ethiopian forces away from the border through Tigray.
The second explanation is the more consequential one.
From Asmara's perspective, backing forces hostile to Addis Ababa could create a buffer. A militarily divided northern Ethiopia would be less able to launch an operation against Eritrea.
The strategy carries an obvious risk. By getting involved in Tigray, Eritrea may give Addis Ababa grounds to justify retaliation.
Eritrea denies supporting the TPLF and rejects Ethiopia's accusations of intervention. Those denials must be weighed separately from independently documented or reported troop movements.
Strategic calculations tend to obscure the human cost. Tigray's communities have already absorbed enormous losses. Another round of competition between Addis Ababa and Asmara would turn their homeland into the battlefield for a struggle whose stakes go well beyond their political future.
Egypt, Sudan and Somalia: The Regional Equation
The danger grows when the wider neighbourhood enters the picture.
Egypt has a long-running dispute with Ethiopia over the Grand Ethiopian Renaissance Dam and the management of Nile waters. Cairo also maintains close relations with Eritrea.
The Critical Threats Project's 8 October assessment documented intensifying diplomatic coordination between Egypt, Eritrea, Somalia and Sudan, against the backdrop of Ethiopia's maritime ambitions and the northern conflict.
A regional declaration stressing sovereignty and territorial integrity may be entirely consistent with international law. In the current climate, it also sends a message: Ethiopia's neighbours are worried about the regional fallout of Addis Ababa's policies.
Somalia has its own grievances. Ethiopia's earlier agreement with Somaliland over maritime access challenged Mogadishu's view of Somali sovereignty.
Sudan adds another layer. Its civil war has already produced rival alliances, military networks and accusations of foreign interference.
In its analysis of the renewed Tigray war, Chatham House described reports of a transnational alignment linking the TPLF, Eritrea and Sudanese armed actors.
These relationships do not show that Egypt, Somalia or Sudan are preparing to fight Ethiopia directly. Ethiopian allegations that they back insurgents are not independent proof of that either.
What they do show is growing strategic polarisation. A confrontation that starts in northern Ethiopia could reach the Nile basin, the Sudanese war and the approaches to the Red Sea.
The Gulf Dimension: Two Powers, Different Relationships
Gulf states matter here because the Horn of Africa cannot be separated from Red Sea security.
On 13 October, Al Jazeera examined the positions of the United Arab Emirates and Saudi Arabia, covering their strategic interests and the limits of what can currently be established about their influence on the fighting.
The UAE has publicly backed Ethiopia's federal government while calling for de-escalation, civilian protection and respect for the Pretoria agreement. It also has significant commercial interests in regional port infrastructure, including Berbera in Somaliland.
These ties give Abu Dhabi influence and channels of communication. They do not, on their own, prove current Emirati military involvement in the renewed fighting.
Saudi Arabia is in a different position. Riyadh helped facilitate the 2018 rapprochement between Ethiopia and Eritrea and has explored mediation before.
According to the same 13 October reporting, however, Saudi Arabia has not announced a new mediation initiative capable of containing the current escalation.
For both countries, an expanded war would reach well beyond Ethiopia and Eritrea.
The Red Sea is already under strain from the Yemen conflict and threats to maritime security. Another major confrontation on its African shore would add instability to a corridor central to international trade.
It would be premature to call the crisis a Saudi-Emirati proxy war. But the potential for competing external interests to complicate diplomacy should not be underestimated.
The Human Cost: A Region That Cannot Afford Another War
Strategic discussions reduce Tigray to roads, mountains, supply lines and buffer zones, and the speed of that reduction is disturbing.
For the people who live there, these are not abstract military coordinates. They are the places where families are trying to rebuild homes, reopen businesses, farm land and send children back to school.
According to The New Humanitarian's 12 October assessment, roughly one million people remain displaced in Tigray, and nearly four million need urgent assistance.
The humanitarian situation is already fragile. Renewed fighting threatens food deliveries, health services and further displacement.
The consequences could extend beyond Ethiopia's borders.
Reuters reported on 12 October, citing updated figures from the International Organization for Migration, that at least 139 migrants died after a vessel travelling from Djibouti toward Yemen capsized.
That disaster should not be presented as a direct result of the latest fighting in Tigray. The route predates the current escalation and is shaped by poverty, insecurity and many other pressures.
It is still a painful reminder of how vulnerable people already are across the Horn of Africa and the Red Sea.
Another regional war would deepen those vulnerabilities and could force more people into impossible choices.
Three Possible Paths to the Next Crisis
1. A Prolonged Proxy Confrontation
This is the most credible near-term scenario.
Eritrea could keep supporting anti-government actors without openly launching a large-scale campaign inside Ethiopia. Addis Ababa could respond by strengthening allied militias and backing groups hostile to Asmara.
Such a confrontation could last months or longer. It would devastate communities without necessarily producing a decisive military result.
The central danger is that a proxy war escalates through miscalculation, especially when armed groups operate near an international border.
2. A Direct Ethiopia-Eritrea War
This is the most immediate and potentially transformative escalation.
Confirmed Ethiopian operations inside Eritrea, especially toward Assab, would change the nature of the crisis. So would a major Eritrean offensive deeper into Ethiopia.
The two states fought a destructive border war from 1998 to 2000. A new conflict would unfold in a more complicated regional environment, with drones, fragmented internal alliances and external interests shaping military decisions.
Neither side could safely assume a short operation would stay limited. Even a tactical success could trigger a much larger confrontation.
3. A Wider Horn of Africa Conflagration
The worst case involves several conflicts interacting, not a single expanding battlefield.
A direct Ethiopia-Eritrea war could intensify rivalry involving Egypt, Sudan and Somalia. Armed groups might seek cross-border support, and external powers could increase political, financial or military backing for their preferred partners.
The war in Sudan and instability around the Red Sea would make diplomatic containment much harder.
The current evidence does not establish this outcome. It is a scenario, not a prediction. But because these crises are geographically close and relations between regional actors are growing more hostile, responsible governments should take the possibility seriously.
What Could Still Prevent a Regional War?
Escalation can still be contained, for three reasons.
First, neither Ethiopia nor Eritrea can assume a new interstate war would be cheap or politically manageable. Both would face serious economic and humanitarian costs.
Second, Ethiopia's maritime problem does not require a territorial solution. Negotiated port access, commercial arrangements and internationally guaranteed transit rights are alternatives to military confrontation.
Third, external powers have channels that could encourage restraint. Saudi Arabia has experience in Ethiopia-Eritrea diplomacy. The UAE maintains close relations with Addis Ababa. The African Union, the United Nations and regional actors could also help de-escalate.
Mediation, however, has to address the actual sources of the crisis. A ceasefire in Tigray alone would not settle the Assab dispute. A port agreement alone would not resolve Ethiopia's internal conflicts. A diplomatic declaration means little without credible commitments against cross-border military intervention.
The immediate priorities are clear: independently verify troop movements, prevent military operations around Assab, restore channels between Addis Ababa and Asmara, protect humanitarian access, and revive a credible political process in Tigray.
Any durable settlement must also recognise Eritrea's sovereignty and Ethiopia's legitimate need for reliable commercial access to the sea.
TLF Conclusion: The Danger Is Real, but War Is Still a Choice
Will Ethiopia's push for direct maritime access and Eritrea's apparent support for armed forces in Tigray ignite another regional war?
Our assessment: these two developments create a serious risk of war, but they have not made a wider conflict unavoidable.
The evidence available on 13 October supports concern about a growing military confrontation, including reported Eritrean movements inside Tigray and Ethiopian drone strikes against Eritrean forces. It also supports concern about regional polarisation involving Egypt, Somalia, Sudan and Gulf actors.
It does not yet establish that Ethiopia has launched a confirmed campaign to seize Assab, or that regional powers have decided to enter a direct war.
That distinction matters.
In a crisis, it is tempting to treat every military movement as proof of a predetermined outcome. But wars are not natural disasters. They come from decisions, miscalculations, fears and opportunities that leaders choose either to exploit or to restrain.
Ethiopia has real economic reasons to seek dependable access to the Red Sea. Eritrea has an equally real right to defend its internationally recognised territory. Neither goal requires the other's destruction.
For Tigray, the danger is more immediate. Its people risk being trapped again between military forces pursuing incompatible political goals.
The deeper tragedy would be for the Horn of Africa to discover, after another generation of suffering, that the access and security arrangements its governments fought over could have been negotiated without war.
The next few days may not decide whether the whole region goes to war. They could decide whether its leaders still have a realistic chance to prevent it.
