People with Albinism in Tanzania are at risk.

Their body parts fetch high prices for witchcraft. Most of the victims are children and survivors are often in dire need of medical treatment.

On Saturday four children who lost limbs in the superstition-driven attacks, arrived in the United States for medical attention.

The New York-based GMRF hosts children from around the world who have been injured in conflict or disaster.

Many need prosthetics like the children from Tanzania, where people with albinism live in danger.

According to the Office of the U.N. High Commissioner for Human Rights, the body parts are traded in a lucrative market for use in witchcraft. Reported prices range from $2,000 for a limb to $75,000 for a corpse.
