Eritrea denies troop movement inside northern Ethiopia as US calls for de-escalation.

Ethiopian forces and allied fighters say they have expanded control across Tigray and entered the historic city of Aksum, as fighting in the northern region continues.

The pro-government militia, the Tigray Peace Force (TPF), also claimed on Thursday that troops from neighbouring Eritrea have retreated towards the border.

Solomon Hailemariam, spokesperson for the TPF, said Eritrean forces had sustained significant casualties during the fighting.

But Eritrea’s Information Minister Yemane Gebremeskel rejected the claims as false in comments to local media. The extent of the reported losses could not be independently verified.

The Armed Conflict Location & Event Data Project (ACLED), an independent conflict-monitoring organisation, documented Ethiopian government forces and TPF fighters entering Aksum, while rival Tigrayan fighters remained in surrounding mountainous areas.

ACLED also reported Eritrean troops withdrawing across the border through Zalambessa, following advances by Ethiopian forces and their allies into several strategic towns.

“Ethiopian troops are on one side, and Eritrean troops are on the other,” Selam, a resident of Zalambessa whose first name was changed for security reasons, told the AFP news agency on Thursday.

AFP reported that there is no fighting now, but the town has been without power or water for a week.

“We are caught in the middle and living in deep anxiety,” Salem told the news agency.

Trading accusations

ACLED also documented Ethiopian tanks and heavy weapons moving towards the Eritrean border on Tuesday, raising concerns about a possible confrontation between the neighbouring countries.

Addis Ababa has accused Eritrea, as well as Sudan and Egypt, of backing a rebel alliance of seven groups that is fighting the government of Abiy Ahmed.

Eritrea has denied accusations that its forces entered Tigray to support the armed opposition groups, accusing Ethiopia of threatening its sovereignty.

Eritrea, which fought alongside Ethiopia’s federal army in the 2020-2022 war, severed diplomatic ties with Ethiopia over the accusations earlier this month.

Khartoum and Cairo have also denied involvement in the conflict.

The TPF supports Ethiopia’s federal government in its campaign against the Tigrayan rebels linked to the Tigray People’s Liberation Front (TPLF).

Ethiopian forces captured Tigray’s regional capital Mekelle earlier this month, and the TPLF confirmed that it had withdrawn from the city and moved its regional administration “temporarily” to another location. Government forces also retook the towns of Adwa and Adigrat from the TPLF without a fight. Further, there are reports of Ethiopian advances in the town of Rama, close to the border with Eritrea.

On Wednesday, US Secretary of State Marco Rubio called for de-escalation in a phone call with Ethiopian Prime Minister Abiy, following reports of the alleged confrontation between Ethiopian and Eritrean forces.

Rubio said the region could not tolerate more conflict, according to a statement from the US Department of State.
