The rainy season is over and the Niger Delta is lush and humid. This southern edge of West Africa, where Nigeria's wealth pumps out of oil and gas fields to bypass millions of its poorest people, is a restless place. In the small delta state of Akwa Ibom, the tension and the poverty has delivered an opportunity for a new and terrible phenomenon that is leading to the abuse and the murder of hundreds, perhaps thousands, of children. And it is being done in the name of Christianity.Almost everyone goes to church here. Driving through the town of Esit Eket, the rust-streaked signs, tarpaulins hung between trees and posters on boulders, advertise a church for every third or fourth house along the road. Such names as New Testament Assembly, Church of God Mission, Mount Zion Gospel, Glory of God, Brotherhood of the Cross, Redeemed, Apostalistic. Behind the smartly painted doors pastors make a living by 'deliverances' - exorcisms - for people beset by witchcraft, something seen to cause anything from divorce, disease, accidents or job losses. With so many churches it's a competitive market, but by local standards a lucrative one.
But an exploitative situation has now grown into something much more sinister as preachers are turning their attentions to children - naming them as witches. In a maddened state of terror, parents and whole villages turn on the child. They are burnt, poisoned, slashed, chained to trees, buried alive or simply beaten and chased off into the bush.
Some parents scrape together sums needed to pay for a deliverance - sometimes as much as three or four months' salary for the average working man - although the pastor will explain that the witch might return and a second deliverance will be needed. Even if the parent wants to keep the child, their neighbours may attack it in the street.
This is not just a few cases. This is becoming commonplace. In Esit Eket, up a nameless, puddled-and-potholed path is a concrete shack stuffed to its fetid rafters with roughly made bunk beds. Here, three to a bed like battery chickens, sleep victims of the besuited Christian pastors and their hours-long, late-night services. Ostracised and abandoned, these are the children a whole community believes fervently are witches.
Sam Ikpe-Itauma is one of the few people in this area who does not believe what the evangelical 'prophets' are preaching. He opened his house to a few homeless waifs he came across, and now he tries his best to look after 131.
'The neighbours were not happy with me and tell me "you are supporting witches". This project was an accident, I saw children being abandoned and it was very worrying. I started with three children, then every day it increased up to 15, so we had to open this new place,' he says. 'For every maybe five children we see on the streets, we believe one has been killed, although it could be more as neighbours turn a blind eye when a witch child disappears.
'It is good we have this shelter, but it is under constant attack.' As he speaks two villagers walk past, at the end of the yard, pulling scarfs across their eyes to hide the 'witches' from their sight.
Ikpe-Itauma's wife, Elizabeth, acts as nurse to the injured children and they have called this place the Child Rights and Rehabilitation Network, a big name for a small refuge. It has found support from a charity running a school in the area, Stepping Stones Nigeria, which is trying to help with money to feed the children, but the numbers turning up here are a huge challenge.
Mary Sudnad, 10, grimaces as her hair is pulled into corn rows by Agnes, 11, but the scalp just above her forehead is bald and blistered. Mary tells her story fast, in staccato, staring fixedly at the ground.
'My youngest brother died. The pastor told my mother it was because I was a witch. Three men came to my house. I didn't know these men. My mother left the house. Left these men. They beat me.' She pushes her fists under her chin to show how her father lay, stretched out on his stomach on the floor of their hut, watching. After the beating there was a trip to the church for 'a deliverance'.
A day later there was a walk in the bush with her mother. They picked poisonous 'asiri' berries that were made into a draught and forced down Mary's throat. If that didn't kill her, her mother warned her, then it would be a barbed-wire hanging. Finally her mother threw boiling water and caustic soda over her head and body, and her father dumped his screaming daughter in a field. Drifting in and out of consciousness, she stayed near the house for a long time before finally slinking off into the bush.Mary was seven. She says she still doesn't feel safe. She says: 'My mother doesn't love me.' And, finally, a tear streaks down her beautiful face.
Gerry was picked out by a 'prophetess' at a prayer night and named as a witch. His mother cursed him, his father siphoned petrol from his motorbike tank and spat it over his eight-year-old face. Gerry's facial blistering is as visible as the trauma in his dull eyes. He asks every adult he sees if they will take him home to his parents: 'It's not them, it's the prophetess, I am scared of her.'
Nwaeka is about 16. She sits by herself in the mud, her eyes rolling, scratching at her stick-thin arms. The other children are surprisingly patient with her. The wound on her head where a nail was driven in looks to be healing well. Nine- year-old Etido had nails, too, five of them across the crown of his downy head. Its hard to tell what damage has been done. Udo, now 12, was beaten and abandoned by his mother. He nearly lost his arm after villagers, finding him foraging for food by the roadside, saw him as a witch and hacked at him with machetes.
Magrose is seven. Her mother dug a pit in the wood and tried to bury her alive. Michael was found by a farmer clearing a ditch, starving and unable to stand on legs that had been flogged raw.
Ekemini Abia has the look of someone in a deep state of shock. Both ankles are circled with gruesome wounds and she moves at a painful hobble. Named as a witch, her father and elders from the church tied her to a tree, the rope cutting her to the bone, and left the 13-year-old there alone for more than a week.
There are sibling groups such as Prince, four, and Rita, nine. Rita told her mum she had dreamt of a lovely party where there was lots to eat and to drink. The belief is that a witch flies away to the coven at night while the body sleeps, so Rita's sweet dream was proof enough: she was a witch and because she had shared food with her sibling - the way witchcraft is spread - both were abandoned. Victoria, cheeky and funny, aged four, and her seven-year-old sister Helen, a serene little girl. Left by their parents in the shell of an old shack, the girls didn't dare move from where they had been abandoned and ate leaves and grass.
The youngest here is a baby. The older girls take it in turn to sling her on their skinny hips and Ikpe-Itauma has named her Amelia, after his grandmother. He estimates around 5,000 children have been abandoned in this area since 1998 and says many bodies have turned up in the rivers or in the forest. Many more are never found. 'The more children the pastor declares witches, the more famous he gets and the more money he can make,' he says. 'The parents are asked for so much money that they will pay in instalments or perhaps sell their property. This is not what churches should be doing.'
Although old tribal beliefs in witch doctors are not so deeply buried in people's memories, and although there had been indigenous Christians in Nigeria since the 19th century, it is American and Scottish Pentecostal and evangelical missionaries of the past 50 years who have shaped these fanatical beliefs. Evil spirits, satanic possessions and miracles can be found aplenty in the Bible, references to killing witches turn up in Exodus, Deuteronomy and Galatians, and literal interpretation of scriptures is a popular crowd-pleaser.
