On 7 August 2014, when sentencing two former Khmer Rouge leaders to life imprisonment, Cambodian judge Nil Nonn said there were evidences of "a widespread and systematic attack against the civilian population of Cambodia". He said the leaders, Nuon Chea, the regime's chief ideologue and former deputy to late leader Pol Pot and Khieu Samphan, the former head of state, together in a "joint criminal enterprise" were involved in murder, extermination, political persecution and other inhumane acts related to the mass eviction of city-dwellers, and executions of enemy soldiers. In November 2018, the trial convicted Nuon Chea and Khieu Samphan of crimes against humanity and genocide against the Vietnamese, while Nuon Chea was also found guilty of genocide relating to the Chams.
