The president of South Sudan has told the BBC that if his side has committed abuse in recent clashes they would be punished.

Speaking as the UN is sending additional troops to try to protect civilians, President Salva Kiir said his government did not start the current conflict and it could not be resolved militarily.

More than 1,000 people have died in the violence which has erupted.

James Copnall reports from Juba.
