South Sudan: UN makes grim discoveries in Bentiu
The United Nations says the ongoing conflict in South Sudan has a disturbing echo of events in Rwanda 20 years ago.
Toby Lanzer, the UN's top humanitarian official, said piles and piles of bodies were left in the town of Bentiu following an attack last week by fighters loyal to the former Vice President Riak Machar.
Mr Lanzer described the killings as ethnically targeted and said it could be a game changer in the fighting.
