Child witchcraft allegations are increasing in parts of Africa, as thousands of children have been attacked, beaten or killed, according to a new report.

...The accused children are mostly boys, ages 8 to 14... [and] often suffer from extreme physical or psychological violence as a result of being branded a "child witch," the report said.

Exorcisms that include pouring petrol into children's eyes or ears, and forcing them to swallow various substances have been reported by researchers as ways to "cleanse" the accused.

These witch-doctors are not unrelated to the heads of BP.
