South Sudan's government has sent troops to provide security at a United Nations base where at least 48 people were killed in an attack.

Almost 5,000 civilians were sheltering at the camp in Bor when armed youths broke through the gates and opened fire.

Bor has been the scene of heavy fighting, having been taken and lost twice by rebels.
