Ethiopia's Prime Minister Abiy Ahmed confirmed for the first time on Tuesday that troops from neighbouring Eritrea entered the northern Tigray region during the five-month-old conflict, the first such acknowledgement after months of denials.
In a parliamentary address, he also acknowledged for the first time that atrocities like rape had been committed during the fighting, and promised perpetrators would be punished.
Fighting erupted in Tigray after forces loyal to the then-governing party there - the Tigray People's Liberation Front (TPLF) - attacked army bases across the region overnight and in the early hours of November 4.
The attacks initially overwhelmed the federal military, which later launched a counter-offensive alongside Eritrean soldiers and forces from the neighbouring region of Amhara.
The TPLF, which dominated Ethiopia's government for nearly three decades until Abiy came to power in 2018, has long been an archenemy of Eritrea.
Abiy said Eritrean troops had crossed the border because they were concerned they would be attacked by TPLF forces, but the Eritreans had promised to leave when Ethiopia's military was able to control the border. The TPLF repeatedly fired rockets at Eritrea after the conflict began.
The governments of both Eritrea and Ethiopia repeatedly denied Eritrea's involvement in the war, despite reports from rights groups like Human Rights Watch and Annesty International, which documented the killings of hundreds of civilians by Eritrean soldiers in the holy city of Axum.
The journalists on a trip to Tigray last week saw hundreds of men wearing Eritrean uniforms in buses with Eritrean plates on the main road between the regional capital Mekelle and Shire, and on the main streets of Shire.
Abiy quoted the Eritreans as saying to Ethiopian authorities: "You left the trenches while searching for the enemy in central Tigray. So, while you attacked them, they might come to us. We controlled areas along the border because we have our national security concerns. But if your army can control the trenches, we will leave the next day."
He said the Ethiopian government had also raised accusations of widespread looting and rights abuses by Eritrean soldiers in Tigray.
"The Eritrean government has highly condemned it and said they will be accountable if any of their army participated in this," he said.
Dozens of witnesses in Tigray said that Eritrean soldiers routinely killed civilians, gang-raped and tortured women and looted civilian households and crops. Some provided images of Eritrean trucks loaded with household goods.
Eritrea's minister of information was not immediately available for comment.
