Traditional religions embody such concepts as monotheism, animism, vitalism, spirit and ancestor worship, witchcraft, and sorcery and vary widely among ethnic groups. The syncretic sects often merge elements of Christianity with traditional beliefs and rituals and are not recognized by mainstream churches as part of Christianity. New variants of ancient beliefs have become widespread, led by US-inspired Pentecostal churches which have been in the forefront of witchcraft accusations, particularly against children and the elderly. Children accused of witchcraft are sent away from homes and family, often to live on the street, which can lead to physical violence against these children. There are charities supporting street children such as the Congo Children Trust. The Congo Children Trust's flagship project is Kimbilio, which works to reunite street children in Lubumbashi. The usual term for these children is ''enfants sorciers'' (child witches) or ''enfants dits sorciers'' (children accused of witchcraft). Non-denominational church organizations have been formed to capitalize on this belief by charging exorbitant fees for exorcisms. Though recently outlawed, children have been subjected in these exorcisms to often-violent abuse at the hands of self-proclaimed prophets and priests.
