Chum Manh (R), 78, a survivor of the Khmer Rouge S-21 torture centre, wipes away tears while people pray at the Tuol Sleng Genocide Museum in Phnom Penh, August 31, 2009, as they boycott the Khmer Rouge trial of Duch, the chief of the S-21. A group of 28 civil parties, many of them who survived the S-21 where more than 14,000 prisoners died after harsh interrogations, boycotted the trial as they are disappointed with the court order not to question the personal character of Duch.
