The United Nations has said it fears casualties, after attackers forced their way into a peacekeeping base in South Sudan's Jonglei state.
Rebels from the country's second-largest ethnic group, the Nuer, attacked the base, targeting civilians of the majority Dinka ethnic community.
UN spokesman Farhan Haq said he condemned the storming of the base ''in the strongest terms''.
