Eagle-eyed Valerie Voigt has again sent me an important link.  It is to a UN publication on contemporary persecution of witches.  It is called

Witchcraft Allegations, Refugee Protection and Human Rights: A Review
of the Evidence, produced by the United Nations High Commissioner for Refugee

Paraphrasing briefly from its abstract:
This paper examines the link between witchcraft accusations and
displacement through forced exile
or fleeing from the threat of harm. The paper provides documented examples of persecution aimed at alleged
witches in various countries before turning to
particular risk groups: women, the elderly and children. Additionally,
albinos in East Africa face persecution not because of alleged
witchcraft activity, but because they are being killed for their body
parts, which are thought to bring good luck.

In the
majority of stories surveyed, individuals confessed unwillingly and persecution is
typically based on beliefs that are imputed upon the accused. Sometimes governments help prevent persecution, sometimes they foster it.  The paper also makes recommendations for organizations working with affected populations.
