ADDIS ABABA, Ethiopia (AP) — Ethiopia's government Tuesday for the first time acknowledged the involvement of troops from neighboring Eritrea in the war in the Tigray region that ended in 2022, accusing them of mass killings, amid reports of renewed fighting in the region. Ethiopian Prime Minister Abiy Ahmed, while addressing parliament Tuesday, accused Eritrean troops fighting alongside Ethiopian forces of mass killings in the war, during which more than 400,000 people are estimated to have died.
