A trial is underway in Cambodia for the four most senior surviving members of the Khmer Rouge. The former officials face charges that include crimes against humanity, war crimes, genocide, religious persecution, homicide and torture. The Khmer Rouge is believed to have killed at least 1.7 million Cambodians during the late 1970s. All four of the accused have plead “not guilty” to the charges against them. Stephen Rapp is the U.S. ambassador at large for war crimes issues.

Stephen Rapp, U.S. Ambassador at Large for War Crimes Issues: “This is such a traumatic event in the history of this country that touched on every single person here, a quarter of the population murdered, a country turned back to the year zero. And an understanding of why it happened and how it happened, I think, is really critical to going forward, and that’s, I think, why there’s such an outpouring of interest here and why it’s so important that the international community support this trial to the end.”
