One of the leaders of the former Khmer Rouge regime will be set free after a court in Cambodia ruled today that she was medically unfit to stand trial for genocide, a decision survivors called shocking and unjust.

A SENIOR Khmer Rouge prison guard has told a war crimes tribunal he was forced to send thousands of detainees to an execution site, where they were brutally killed and their bodies thrown into mass graves.

Crusading actress Angelina Jolie paid her respects to victims of the Cambodian genocide with a visit to a former prison in the country's capital.
