Witchcraft has long been practiced throughout Uganda. It's a country where the ancient and the modern meet, with many in rural areas continuing the mystical beliefs of their ancestors, while in cities there's rapid economic development. But from this cultural clash a gruesome phenomenon is growing, and Uganda's children are paying the price. Children are disappearing, victims of human sacrifice, at the hands of so-called 'witch doctors'. It's estimated at least two children go missing each week, often kidnapped for so-called ritualistic sacrifice. Advocates say, the spike has been attributed to poverty, poor policing of witch doctors - and up to 80 per cent of the population seeking health advice from traditional healers.
