Tanzania albinos face violence

In the past 18 months, at least 25 Albinos, including children, have been mutilated and murdered in Tanzania.

Authorities say witch doctors appear to be linked to the killings.

Albinism is especially prevalent in Africa, where it is estimated to affect as many as one in a thousand people.

It occurs when the genes don't produce enough portions of a pigment known as melanin, meaning the skin is extremely pale.
