Ethiopia's prime minister and a rebel group have traded blame for a mass killing in Oromiya, the country's most populous region, where hundreds of people have died in recent months in escalating violence.
The latest killings took place on Monday in two villages in Kellem Wollega zone, around 400 km (250 miles) west of the capital Addis Ababa, the state-appointed Ethiopian Human Rights Commission (EHRC) said.
Both the EHRC and Prime Minister Abiy Ahmed blamed the Oromo Liberation Army (OLA), a banned splinter group of an opposition party, for the killings, which Abiy called a "massacre".
