Sri Lanka 'war crimes' video: who are these men?

Channel 4 News reveals images of the men caught on camera apparently taking part in executions in Sri Lanka, actions a top lawyer has branded "war crimes". Can you help identify the men involved?

The UN has told Channel 4 News that the Sri Lanka apparent execution video, broadcast on Tuesday, deserves further investigation.

The UN Special Rapporteur on extrajudicial, summary or arbitrary executions, Professor Christof Heyns, said: "It is shocking indeed, and clearly deserves more investigation," he said.

Mark Ellis, Executive Director of the International Bar Association (IBA), told Channel 4 News the video was prima facie evidence of war crimes being committed.
