The issue of "child witches" is soaring in Nigeria and other parts of the world, Foxcroft said.

The states of Akwa Ibom and Cross River have about 15,000 children branded as witches, and most of them end up abandoned and abused on the streets, he said.

Christian ran away from home and wandered around for two years with other children similarly accused. He said they stole, begged for food and performed menial jobs to survive.

The plight of "child witches" is raising concern among aid organizations, including the United Nations.

"It is a growing issue worldwide, among not just African communities, but in countries such as Nepal as well," said Jeff Crisp, head of policy development and evaluation for the U.N. High Commissioner for Refugees. "We are trying to see whether it is a neglected protected issue."

Belief in witchcraft thrives worldwide. About 1,000 people accused of being witches in Gambia were locked in detention centers in March and forced to drink a dangerous hallucinogenic potion, human rights organization Amnesty International said.

In 2005, relatives of an 8-year-old Angolan girl living in England were convicted of torturing her for being a "witch," according to the Times Online.

Pastors have been accused of worsening the problem by claiming to have powers to recognize and exorcise "child witches," sometimes for a fee, aid workers said.

But some are true believers, such as one minister in Lagos, Nigeria. He pinpoints children affected by witchcraft for free, he said.
