Confronting a dark past in Cambodia's Khmer Rouge stronghold

The remote district of Anlong Veng, final resting place of Pol Pot, was the last stronghold of the brutal Khmer Rouge, whose reign of terror left up to two million Cambodians dead in the 1970s. A pioneering new project aims to introduce tour groups of students to former Khmer Rouge cadres so that both generations can learn from the country's tragic past.
