Ethiopia Drones the Army It Once Fought Beside

Ethiopian military drones struck Eritrean vehicles inside Tigray on 7 and 8 October as those troops pulled back from Adigrat. The Armed Conflict Location and Event Data Project recorded the crossing at Zelambesa and the strikes at Guada.

Foreign Minister Gedion Timothewos then told the UN Security Council that Eritrea had launched an “all-out invasion,” advancing up to 60 km into northern Ethiopia, and that Addis Ababa was acting in self-defence.

Eritrean Columns Reached Adigrat, Then Turned North

On 7 October, Eritrean forces crossed at Zelambesa and moved toward the Adigrat to Idaga Hamus road, according to ACLED’s Ethiopia conflict alerts. Ethiopian National Defense Force drones hit those troops at Guada while they were travelling by vehicle toward Idaga Hamus. ACLED said sources identified them by uniforms, vehicles and license plates.

By the next night the same columns were pulling out of Adigrat. ACLED recorded drone strikes on vehicles carrying troops and equipment, with heavy explosions into the morning of 8 October. There have been no verified casualty figures from those hits.

The Critical Threats Project, in a 9 October review by Liam Karr, only partly backed the incursion story and could not fully confirm it. Analysts there still geolocated a struck truck near Adigrat on the southern outskirts, facing north, which matches a force moving back toward Eritrea rather than toward Mekelle.

THE ADIGRAT WINDOW

• The crossing: ACLED dates the Zelambesa move to 7 October, with the first drone hits at Guada on the road to Idaga Hamus.
• The turn: Eritrean forces that had reached Adigrat spent that night withdrawing, under strikes ACLED attributes to the ENDF.
• The wreck: a truck geolocated on Adigrat’s southern edge was facing north, the direction of the border, not the regional capital.
• The claim: Gedion’s letter, dated 8 October, said Eritrean units had pushed as far as 60 km (37 miles) into Tigray.

Idaga Hamus sits 12 miles south of Adigrat. Ermiyas Ababu, a Tigray Peace Force commander in Mekelle, said Eritrean officers had been in Adigrat and then in Idaga Hamus, conducting surveillance. Ethiopia’s communications minister, Enatalem Melese, said those forces had to leave Ethiopian territory without delay.

Asmara Wanted a Buffer on the Road to Assab

The column did not behave like an army racing to Mekelle. It moved onto the Adigrat road as federal units and the Tigray Peace Force were already driving north, then reversed under drones. Jalale Getachew Birru, ACLED’s East Africa analyst, set out Eritrea’s two reasons for entering Tigray.

Eritrea was dissatisfied with the Pretoria agreement, which ended the 2020-2022 war between the TPLF and the Ethiopian government, because Eritrea sought to eliminate the TPLF due to past grievances stemming from the 1998-2000 border conflict. Second, Eritrea opposes Ethiopia’s quest to access the Red Sea through the port of Assab and seeks to create a buffer between Ethiopia and Eritrea by making Tigray hostile to Ethiopia. Hence, Eritrean forces entered the war in Tigray to halt the Ethiopian government and allied forces from reaching the border and potentially fighting within Eritrea’s territory.

Jalale Getachew Birru, East Africa analyst, ACLED

That is the inversion. Eritrea fought with Prime Minister Abiy Ahmed’s government against the Tigray People’s Liberation Front from 2020 to 2022. Four years later, ACLED has Eritrean troops on Tigrayan roads trying to keep Ethiopian units off the frontier, and Ethiopian drones shooting at them.

Yemane Ghebremeskel, Eritrea’s information minister, did not confirm or deny that troops had crossed. “We are not in the business of refuting wild allegations or narratives,” he said. He has instead treated the whole episode as cover for a march on Assab.

The 2018 Peace Left the Sea Unsettled

Eritrea became independent from Ethiopia in 1993 and took the Red Sea coast, including Assab, with it. The two states then fought from 1998 to 2000. A 2018 rapprochement opened the border and won Abiy the Nobel Peace Prize in 2019. Eritrean troops later joined the federal campaign in Tigray.

Eritrea was not a party to the Pretoria Agreement signed on 2 November 2022, which halted that war. Researchers at Ghent University in Belgium have estimated about 500,000 civilian deaths in Tigray from violence, famine and the collapse of health services. Disarmament, disputed land, returns of displaced people and any accounting for crimes were left unfinished, and so was the sea.

Horn Review’s October briefing on what Pretoria left unresolved lists incomplete disarmament, the status of Tselemti and Raya, hundreds of thousands of displaced Tigrayans still unable to go home, Eritrea’s absence from the deal, and deferred accountability. Tigrayan forces did hand over heavy weapons and demobilize more than 60,000 fighters from late 2024, but the process did not finish.

Abiy, sworn in again on 5 October, returned to the same demand. “Based on the principle of give and take, we will work diligently to ensure that Ethiopia has an outlet to the sea,” he told parliament. Ethiopia’s foreign ministry said any serious talk of Red Sea security had to account for the country’s “legitimate interests and its enduring connection to the Red Sea.”

On 4 October, Egypt, Eritrea, Sudan and Somalia answered from New Alamein. Their declaration assigned Red Sea governance to coastal states alone. Yemane, writing on 9 October, dated the war he says Ethiopia is already fighting to a 13 October 2023 speech in which Abiy said the country would gain “sovereign access to the sea, through negotiations if possible and by force if necessary.”

Ethiopia's Ministry of Foreign Affairs is these days accusing Eritrea for acts of "unprovoked aggression that may jeopardize regional peace and security".

Audacity and duplicity in their most extreme forms!

The indelible facts:
1. Ethiopia has in essence declared a war of…

Yemane also wrote that Ethiopia’s army deputy chief of staff said on 27 September, “Mekelle is a mere stop-over, our ultimate destination is Assab,” and that the main objective was “to install our flag in the Red Sea.” Those lines are Eritrea’s account of an Ethiopian officer. They are the reason a short-lived column in Adigrat is being read, in Asmara, as a fight over a port.

Who Holds the Northern Towns Now

While the Eritrean move was being argued in letters, federal units and the Tigray Peace Force were taking the road. ACLED said they took Wukro and Hagere Selam on 7 October, then Idaga Hamus on 9 October, and were expected to take Adigrat next after local officials and the Tigray Defense Forces started leaving on 7 October. The same day they took Shire, Atsibi and Freweyni (Senkata).

Critical Threats described a fast push at least 30 miles north to Adigrat’s outskirts between 8 and 9 October, “without strong resistance.” Wukro is about 31 miles north of Mekelle on the A2. Agula, taken after artillery and drone strikes, is about 35 km northeast of Mekelle.

TOWNS ON THE NORTHERN ROAD

Alamata, about 120 km south of Mekelle, had already been retaken on 28 September. Tigray Defense Forces still held ground off the highway, including around Nebelet, and ACLED said they were heavily present in Atsbi and Kilte Awlaelo near Wukro as of 7 October. The map is a federal road net with TPLF units in the hills, not a finished occupation of Tigray.

Tigray’s Old Army Is Fighting Itself

The Tigray Peace Force, which includes former fighters from the TPLF’s armed wing, entered central Mekelle on 3 October. Federal control of the city was confirmed on 4 October after the TPLF said it had “temporarily moved out of Mekelle” so the city would not be destroyed. Federal police later asked residents to help stand up a new administration. Ethiopian Airlines said it would resume flights to Mekelle on 11 October.

Getachew Reda, who signed Pretoria for the TPLF, now advises Abiy. Lt. Gen. Tadesse Werede, whom Abiy had put in charge of the interim administration, was detained by TPLF forces on 24 September, according to Horn Review. Debretsion Gebremichael still leads the party in the field. The split is the reason Ethiopian units could take the capital with Tigrayan allies while other Tigrayans kept fighting them.

Fighting resumed on 23 September, three days after seven armed movements announced the Alliance for Survival, whose stated aim is to remove Abiy. ACLED later found that only three of those seven, the TPLF, the Amhara Fano National Movement, and the Afar group known as Ugugumo, were actually fighting in the north. Fano itself is divided over working with the TPLF. About 150,000 people had been displaced in Afar by 29 September.

WHAT PRETORIA DID NOT CLOSE

• Disarmament: heavy weapons went in and more than 60,000 fighters left the rolls from late 2024, but mobilisation never fully stopped.
• Land: Tselemti and Raya stayed contested, and large numbers of displaced Tigrayans did not go home.
• Eritrea: Asmara was outside the deal and opposed a settlement that left the TPLF alive.
• The sea: nothing in Pretoria touched Assab, Massawa, or Ethiopia’s claim to a sovereign outlet.

Reports have also described the TPLF forcibly recruiting boys as young as 15. Jalale said civilians in Tigray, Amhara and Afar “didn’t get healed from the first round of violence that was halted by the peace agreement” and “just started healing recently.”

Addis Ababa Invokes Self-Defense at the UN

On 1 October Ethiopia closed its embassy in Asmara and ordered 10 Eritrean diplomats out, citing “direct and indirect acts of hostility and belligerence.” Eritrea severed diplomatic ties. Gedion’s letter of 8 October, sent to French Foreign Minister Jean-Noel Barrot and to the rest of the Security Council, called the troop presence “a blatant act of aggression that engages Ethiopia’s inherent right to self-defence.” He invoked Article 51 of the UN Charter. He did not spell out the measures Ethiopia was taking.

The all-out invasion of parts of northern Ethiopia by Eritrea is a matter of public record. It is a blatant act of aggression that engages Ethiopia’s inherent right to self-defence.

Gedion Timothewos, foreign minister of Ethiopia, letter dated 8 October 2026

“In this time of difficulty, when Ethiopia is left with no other option but to defend itself, we count on your understanding, support, and solidarity,” the letter said. It accused Eritrea of deploying infantry and mechanized units and of supporting, financing, arming and directing insurgent groups. It did not name the occupied places or attach public evidence. Gedion also told UN Deputy Secretary-General Amina Mohammed that Eritrean forces had to withdraw at once.

Yemane’s reply is that Ethiopia has been “incessantly beating the drums of war” for sovereign access to the sea and has “tried to repackage this war agenda in terms of ‘self-defence’ by fabricating various allegations against Eritrea.” Magnus Taylor, Horn of Africa deputy director at the Crisis Group, has warned that Abiy “might try to solve all his problems at the same time, by invading Eritrea, possibly a regime change move and also a land grab for the Red Sea port, and also solving his problem with Tigray at the same time.”

The louder problem in the open argument is not whether a column moved through Adigrat. It is whether that column was a brief buffer meant to keep Ethiopian units off Eritrean soil, and whether the Article 51 letter turns a one-night reverse into a legal path toward Assab. Some circulating videos of the movement have been called old footage. ACLED’s account still rests on uniforms, plates and local witnesses, and the geolocated wreck faced north.

Guterres Asks All Sides to Stop Immediately

The spokesperson for UN Secretary-General António Guterres issued a statement dated 9 October in New York, carried on 10 October as the UN secretary-general’s statement on Ethiopia. Guterres said he was gravely concerned by fighting in Tigray, Afar and Amhara, called on all parties to cease hostilities immediately, and urged the Pretoria signatories to return to dialogue under that framework.

He also said he was concerned by reports of Eritrean forces in Ethiopia. He reminded states in the region of their duty under the UN Charter to refrain from the threat or use of force against another state’s territorial integrity or political independence, and of non-interference. He offered his good offices.

1. 20 September 2026: Seven armed movements announce the Alliance for Survival, aimed at removing Abiy.
2. 23 September 2026: TPLF forces seize the airports at Mekelle, Axum and Shire; fighting spreads into Amhara and Afar.
3. 1 October 2026: Ethiopia closes its Asmara embassy and expels 10 Eritrean diplomats; Eritrea cuts ties.
4. 3 to 4 October 2026: The Tigray Peace Force and federal troops take Mekelle after the TPLF withdraws.
5. 4 October 2026: Egypt, Eritrea, Sudan and Somalia issue the El-Alamein line on Red Sea governance.
6. 5 October 2026: Abiy, sworn in again, says Ethiopia will work for an outlet to the sea.
7. 7 to 8 October 2026: Eritrean forces cross at Zelambesa, reach Adigrat, and withdraw under Ethiopian drones.
8. 8 to 9 October 2026: Gedion’s Article 51 letter goes to the Security Council; Guterres asks for an immediate halt.

WHAT WE KNOW

• The strikes: ACLED attributes drone hits on Eritrean vehicles at Guada and around Adigrat to the ENDF on 7 and 8 October.
• The letter: Ethiopia has told the Security Council it faces an all-out invasion and is acting in self-defence under Article 51.
• The road: ENDF and Tigray Peace Force units hold Mekelle, Wukro, Idaga Hamus, Shire, Atsibi and Freweyni.

WHAT IS UNCONFIRMED

• Eritrea’s order of battle: Asmara has not confirmed troops inside Ethiopia, and CTP still treats the incursion as only partly corroborated.
• Adigrat’s final control: ACLED expected federal forces to take the town after TDF officials left; CTP had them at the outskirts, not in a finished capture.
• Casualties: no verified count from the drone strikes has been published.

Federal units are now on the road that leads to the Eritrean border, the TPLF is still in the hills, and both capitals have described the same week as an attack on their sovereignty. Ethiopian Airlines is due to fly into Mekelle again on 11 October. Guterres has offered to help them stop. Neither government has taken that offer up.
