I've just read an article on the Independent website about a programme called Branded a Witch that was shown on BBC3 last night. It is about one African woman's experiences of being persecuted as a child because her family believed she was a witch. The feature says:
"Kanda ... endured years of abuse before being taken into care. Now 23, and with two young sons of her own, she set out to examine a lethal new twist to the widespread African belief in witchcraft, which has increasingly come to be associated with the abuse and even murder of children."
I didn't see the documentary about this tragic modern form of persecution over witchcraft beliefs, but I'll look out for it on catch-up. The BBC normally keeps documentaries for about a week on BBC iPlayer.
