PHNOM PENH, CAMBODIA – AUGUST 06: A photograph of one of the former Khmer Rouge leaders, Nuon Chea, stands in one of the rooms of Tuol Sleng prison, also known as S-21, on August 6, 2014 in Phnom Penh, Cambodia. S-21 is believed to have held approximately 14,000 prisoners while in operation, most of whom were intellectuals and high-ranking officials, including Khmer Rouge officials accused of treason and espionage. Only 12 survived. One day before Cambodia’s UN-backed court delivers verdicts for two former Khmer Rouge leaders – Nuon Chea, also known as “Brother Number Two”, and Khieu Samphan, the former head of State – some Cambodians remember this tragic period in the country’s history by visiting places related to the genocide in the capital Phnom Penh. In April 1975, the Communist Party of Kampuchea, also known as the Khmer Rouge, seized power in Cambodia, forcibly relocating the population to work in labor camps around the country and imprisoning an increasing number of people. Up until the regime’s overthrow in January 1979, the policies that were put in place resulted in the creation of a state defined by repression and violence. Close to two million people lost their lives, due to forced labor, starvation, torture and executions. (Photo by Omar Havana/Getty Images)
