Chum Manh, 78, a survivor of the Khmer Rouge S-21 torture centre, sits in his former cell during a visit to the Tuol Sleng Genocide Museum in Phnom Penh, August 31, 2009, as he boycotts the Khmer Rouge trial of Duch, the chief of the S-21. A group of 28 civil parties, many of them relatives of prisoners who died after harsh interrogations at S-21, boycotted the trial as they are disappointed with the court order not to question the personal character of Duch.
