The second such attack in a little more than two weeks has left "many" villagers dead. This latest round of attacks against ethnic minorities in western Ethiopia.
According to witnesses who talked to the BBC, farming villages home to members of the Amhara group were targeted.
The Oromo Liberation Army, the armed group that Prime Minister Abiy Ahmed accused of being responsible for the violence, will be "eliminated," he said, calling the tragedy a "massacre."
The gang hasn't yet answered the charges.
In the Hawa Gelan district of the Oromia region, the attacks started at around daybreak on Monday and lasted for at least three hours.
Witnesses informed the BBC that victims were executed without regard for gender, age, or other factors.
Houses were set on fire, and mosques are now housing the survivors.
Although there isn't an official death toll yet, there are worries that it may be substantial.
According to government statistics, similar attacks against minorities roughly two weeks earlier resulted in 338 fatalities. The real number, according to activists, was far higher.
Ethnic conflict in Ethiopia has increased recently, and it appears that the situation is getting worse.
