Protests have been taking place in at least ten towns across Ethiopia's Oromia region to demand official action to stop frequent outbreaks of violence.

Over the past two months, more than 30 people have been killed and tens of thousands have been displaced in the Benishangul-Gumuz region, close to the borders with Sudan and South Sudan.

Seventeen members of the state police force have also been killed.

The federal and regional governments say the violence is being fuelled by people opposed to the political and economic reforms introduced by Ethiopia's prime minister, Abiy Ahmed.

The authorities say more than 200 people have been arrested.
