Oscar-nominated actress Sophie Okonedo (Hotel Rwanda, Secret Life Of Bees) will narrate a "hard-hitting" documentary for the UK's Channel 4, from the people who brought us China's Stolen Children. This time, the subject is children in Nigeria who are tortured for being witches. Expect to hear shocking stories: a 13-year-old was tied up with chicken wire and starved and beaten for two weeks; another 14-year-old girl was burned with acid before her mother attempted to bury her alive. This happens when preachers in poor areas brand children witches or wizards and charge their parents to "exorcise" the spirits. [Guardian]
