Hundreds of civilians, including women and children, have been massacred by rebels who seized an oil-rich town in South Sudan, the United Nations said.
Armed men, believed to be loyal to the former vice-president Riek Machar, swept into Bentiu and systematically shot dead foreigners and people from enemy tribes.
The exact number of people who died is unclear, but at least 200 were killed in the Kali-Ballee mosque in the capital of Unity state, and 400 wounded, the UN Mission in South Sudan said in a statement.
Mr Machar was sacked by President Salva Kiir last July and has been accused of spreading violence and plotting coups.
