Akwa Ibom state, Nigeria (CNN) -- Just after midnight, the pastor seized a woman's forehead with his large hand and she fell screaming and writhing on the ground. "Fire! Fire! Fire!" shouted the worshippers, raising their hands in the air.
Pastor Celestine Effiong's congregants are being delivered from what they firmly believe to be witchcraft. And in the darkness of the city and the villages beyond, similar shouts and screams echo from makeshift church to makeshift church.
"I have been delivered from witches and wizards today!" exclaimed one exhausted-looking woman.
