Troops in Eritrean uniforms are seen on top of a truck near the town of Adigrat, Ethiopia, March 14, 2021.
Forces from Ethiopia's rebellious Tigray recaptured much of the territory in June, in a major setback for Ethiopia's government.
Spokespeople for Eritrea's information ministry, Ethiopia's prime minister and Ethiopia's military did not immediately respond to requests for comment.
Eritrean troops entered Tigray to fight alongside federal forces in a conflict marked by abuses including rape, according to investigations by Reuters, the U.N. and international human rights organizations.
