Prosecutors sum up in trial of surviving Khmer Rouge leaders

Prosecutors in the trial in Cambodia of two surviving leaders of the former Khmer Rouge regime have begun summing up their case, declaring that, despite the defendants' denials, the evidence clearly shows they knew of the suffering and deaths of their countrymen.

Khieu Samphan, the regime's 85-year-old former head of state, and 90-year-old Nuon Chea, right-hand man to the group's late chief, Pol Pot, are being tried in Phnom Penh on charges including genocide, rape and murder.
