Many people with albinism are living in fear in Tanzania
A six-year-old albino girl in Burundi has been found dead with her head and limbs removed, in the latest killing linked to ritual medicine.
Albinos in the region have been targeted because of a belief peddled by witchdoctors that their body parts can be used for magic potions.
The girl, who was attacked on Sunday, was the sixth person with albinism to be killed in Burundi since September.
There have also been a number of attacks in neighbouring Tanzania.
The latest attack took place in Burundi's eastern province of Ruyigi.
The BBC's Prime Ndikumagenge in Burundi said the child and her family had only just returned to their family home.
Armed attackers broke into the family home and tied up the girl's parents before shooting her in the head, local officials say.
They had been among a group of about 50 people with albinism to have fled to a provincial centre because they feared for her safety.
The head of the Burundi Albinos' Association, Kasim Kazungu, says people with albinism had not suffered any discrimination until other Burundians heard about the lucrative trade in albino body parts in neighbouring Tanzania.
Last week, police in south-western Tanzania arrested a man who was attempting to sell his albino wife to Congolese traders.
Two mothers in western Tanzania were also attacked with machetes after gangs failed to find their albino children.
