Police in Ethiopia say two members of the Tigrayan ethnic group have been stoned to death in the Oromia region.

The two farmers, who had lived in the area for decades, are said to have been killed by protesting youths.

Some of the attackers have been arrested while others are on the run.

For decades, a Tigrayan party, the TPLF, dominated power in Ethiopia.

There has been significant change in recent months with the selection of a new Prime Minister, Abiy Ahmed, who comes from the Oromo ethnic group, the largest in the country.
