At least two people have died in protests in Ethiopia where demonstrators accuse a police unit of carrying out killings and human rights abuses against the Oromo people.
The conflict has been raging for months but escalated this week in violent confrontations.
Over 600 have been displaced during the clashes on Tuesday in towns in the east of the country.
The government has blamed the clashes on a border dispute between the Oromo and their neighbours in the Somali region of Ethiopia.
It says it has now sent in the military to carry out a disarmament exercise.
