Malawians with albinism -- a genetic condition resulting in little or no pigmentation in the skin, hair and eyes -- are under threat.
Criminal gangs hunt albinos to kill and dismember them, selling their bones.
Albino bones are used by witchdoctors, who believe the body parts bring wealth, happiness and good luck.
According to Amnesty International, at least 18 albinos have been killed in Malawi since 2014, and five are still missing.
The United Nations warns that Malawi's albinos are at risk of "total extinction."
