BBC discovers Burundi 'murdered rebel graves'

Burundian soldiers shot dead 17 rebels at point-blank range after they surrendered in January, witnesses have told the BBC.

The rebels, with hands raised, were lined up on the edge of the cliff before being killed, one witness said.

Burundi's army denied the allegation, saying 95 rebels were killed in a five-day battle in the remote north-west.
