Evidence of the massacre of at least 321 people in Democratic Republic of Congo has been uncovered by the BBC.
The killings took place last December but have not previously been reported.
Fighters from the notorious Lord’s Resistance Army raided several villages in a remote part of north-eastern DR Congo, killing and abducting children.
Human Rights Watch says this is one of the worst massacres carried out by the LRA, whose fighters roam across several countries after spreading from Uganda.
