From late 1976 onward, and especially in the middle of 1977, the levels of violence increased across Democratic Kampuchea, particularly at the village level. In rural areas, most of the killings were perpetrated by young cadres who were enforcing what they believed to be the government's will. Across the country, peasant cadres tortured and killed members of their communities whom they disliked. Many cadres ate the livers of their victims and tore unborn foetuses from their mothers for use as kun krak talismans. The CPK Central Command was aware of such practices but did nothing to stop them. By 1977, the growing violence, coupled with poor food, was generating disillusionment even within the Khmer Rouge's core support base. Growing numbers of Cambodians attempted to flee into Thailand and Vietnam. In the autumn of 1977, Pol Pot declared the purges at an end. According to the CPK's own figures, by August 1977 between 4000 and 5000 party members had been liquidated as "enemy agents" or "bad elements".
