Evidence that more than 300 people were killed by rebels in the Democratic Republic of Congo has been uncovered following an investigation by the BBC and Human Rights Watch.
The killings took place last December and were carried out by the Lord's Resistance Army
Human Rights Watch said this was one of the worst massacres carried out by the LRA.
The killing spree, in which at least 321 are reported to have been killed, took place in villages in the country’s remote northeast and followed warnings of rebel threats after similar massacres in 2008.
News of the killings will fuel the debate over the role and future of the much-criticised UN mission, which complains it lacks resources to protect civilians but is also under pressure from the Congolese government to pull out by next year.
The UN has a base at Niangara, about 50 km to the east of the capital Kinshasa, though there are fewer than 100 troops and no helicopters.
