An investigation by BBC Africa Eye has uncovered evidence that a massacre in northern Ethiopia was carried out by members of the Ethiopian military. It also reveals the precise location of the atrocity, in which at least 15 men were killed.

In early March, a series of five video clips surfaced on social media showing armed, uniformed men leading a group of unarmed men to the edge of a cliff, shooting some at point blank range, and pushing dead bodies over the cliff.

The BBC has confirmed that the massacre took place close to the town of Mahbere Dego in Ethiopia’s northern Tigray region, where the Ethiopian army is fighting the forces of the Tigray People’s Liberation Front (TPLF), previously the region’s ruling party.
