South Sudan fighting continues as refugee conditions worsen

Fighting is continuing unabated in South Sudan as the two sides prepare to begin peace talks in Ethiopia.

Meanwhile, aid agencies say supplies are urgently needed for the many thousands of people forced to flee their homes.

Conditions have deteriorated in Awerial refugee camp on the banks of the Nile - now home to some 75,000 people who have fled the fighting in nearby Bor, the capital of Jonglei state, now in rebel hands.
