Chankiri Tree
A Chankiri Tree or Killing Tree is a tree in the Cambodian Killing Fields against which children and infants were smashed because their parents were accused of crimes against the Khmer Rouge. It was so the children "wouldn't grow up and take revenge for their parents' deaths". Some of the soldiers laughed as they beat the children against the trees, as not laughing could have indicated sympathy, making oneself a target.
