PHNOM PENH, CAMBODIA - MAY 2:  Pictures of former prisoners, here a mother with an infant, on display in the infamous S-21 prison May 2, 2007 in Phnom Penh, Cambodia. The former prison is now a genocide museum that bears testament to the horrendous acts committed by the Khmer Rouge on its own people. The S-21prison, or Toul Sleng as it was also known, was the Khmer Rouge's most brutal prison. It was here that alleged enemies of Pol Pot's communist revolution underwent brutal torture until they admitted to committing fictitious crimes against the revolution. It is believed that more than 14000 people lost their lives either in the prison on when their death sentences were being carried out in the Killing Fields on the outskirts of the city. Only a handful has been known to survive, most notably seven people who were alive when the Vietnamese invaded the country in 1979. (Photo by David Hogsholt/Reportage by Getty Images)
