The UN mission in South Sudan says at least 13 people have been killed in inter-communal fighting at a camp in the northern part of the country.
The clashes between two ethnic communities in Malakal began on Thursday after a man was stabbed to death.
More than 20 people were injured with some needing hospital treatment.
The Malakal camp – which was set up at the start of the civil war in 2013 – is home to at least 50,000 people.
