The United Nations remains concerned about the situation in South Sudan where fighting has broken out between government and rebel forces.

The situation is reported to be tense as government forces prepare to retake the town of Bor in Jonglei State which was seized by rebellious troops last week.

Thousands of people have been displaced by the fighting between the Dinka and Nuer communities in the new nation.

The seeds of the crisis are reported to have been planted in July when President Salvar Kiir, a Dinka sacked former Vice President Riek Machar from the Nuer community.
