Sri Lanka is facing fresh calls for an international human rights inquiry after video emerged apparently showing extra-judicial killings by troops.
The footage - edited here only to remove the most disturbing images - was supplied by a group called Journalists for Democracy in Sri Lanka, which claims the footage was shot in January.
It shows a man dressed as a soldier shooting a prisoner in the head. Eight other bodies are seen on the ground.
It is impossible for the BBC to verify the video's authenticity. Sri Lanka's government says the footage was fabricated - and in a press release it said it "strongly and unequivocally" denied the allegations.
This video contains images which viewers may find disturbing.
