The UN special Representative for South Sudan says UMINSS must be allowed to access the conflict affected areas to document the crimes.

In a statement, Ellen Margrethe Loj says those who commit gross human rights violations must be held accountable.

Ms Loj made the remarks following her visit to the UNMISS Protection of Civilian Site in Bentiu.

The statement also says the PoC site has been expanded to give shelter to all displaced people.

UNMISS says more than 60, 000 people have sought shelter at its Bentiu camp, and nearly 2500 in Malakal.
