A three-year-old boy in Kayseri has died after rocks broke loose from a cliff face and struck him. The child was sitting on his father's lap when the debris came down, giving him no chance to move clear. The fragments hit the boy on the head and left him critically injured. He was taken to hospital, where doctors could not keep him alive. The father now has to live with the fact that he was holding his son in the very moment the stones fell. The accident is likely to prompt questions about safety and warning measures around rock-strewn slopes in the province.
