Cambodians wait to attend the trial of Kaing Guek Eav -- also known as Duch -- at the Extraordinary Chamber in the Courts of Cambodia (ECCC) in Phnom Penh. Prosecutors have called for the former Khmer Rouge prison chief to get a lengthy jail term, saying he embodied the ruthless efficiency of the regime behind the 'Killing Fields' atrocities.
