The Khmer Rouge Tribunal reacted with some surprise in Phnom Penh yesterday when Nuon Chea, Brother Number Two of the Khmer Rouge, told a civilian victim who had lost his parents to the Khmer Rouge. "I am bearing the responsibility from my heart." The articulate 86-year-old Khmer Rouge leader, who is in indifferent health, was speaking from his holding cell by video link to the court, when he said: "I, of course, was one of the leaders so I am not rejecting responsibility. In my capacity as a member of Democratic Kampuchea, I accept my responsibility. I express my sincere condolences to you for the loss of your family."
