Border clashes between Ethiopia’s Afar and Somali regions have killed at least 100 civilians, many of them herders, since clashes broke out on Friday and continued through to Tuesday, the deputy police commissioner for the Afar region said, blaming the violence on an attack by Somali regional forces. Clashes along the border predate the six-month-old conflict in the north that has pitted the federal government against the former ruling party in the Tigray region. But the violence has intensified just as Prime Minister Abiy Ahmed’s government is trying to assert control over the region.
