Hundreds of civilians killed in South Sudan ethnic massacre - U.N.

UNITED NATIONS (Reuters) - Rebels slaughtered hundreds of civilians when they seized the South Sudan oil hub of Bentiu, hunting down men, women and children who had sought refuge in a hospital, mosque and Catholic church, the United Nations said on Monday.

Rebel troops overran Bentiu, the capital of the oil producing Unity State, on Tuesday. More than 1 million people have fled their homes since fighting erupted in the world's youngest country in December between troops backing President Salva Kiir and soldiers loyal to his sacked vice president, Riek Machar.
