In the photograph above, 6-month old Jennifer, an albino girl, plays with beads outside her home in Tanzania. This African country has the world's largest proportion of albinos, but discrimination and violence against this population run high: in the past 20 months, 57 people with albinism have been hunted and their bodies butchered for parts used in ceremonies.

More at this National Geographic online feature, which includes video: Albino Murders. A related documentary will air Tuesday night on the National Geographic channel, at 10pm.
