Witch hunt
The  UNHCR say that such witch hunts usually are a massive violation of human rights. Most of the accused are women and children but can also be elderly people or marginalised groups of the community such as albinos and the HIV-infected. These victims are often considered burdens to the community.  As as a result they are often driven out, starved to death, or killed violently, sometimes by their own families in acts of social cleansing. The causes of witch-hunts include poverty, epidemics, social crises and lack of education. The leader of the witch-hunt, often a prominent figure in the community or a "witch doctor", may also gain economic benefit by charging for an exorcism or by selling body parts of the murdered.
