Dozens of villagers in the Kenyan district of Kisii are falling prey to superstitious groups accusing them of witchcraft.

The poverty-stricken district, known as Kenya's sorcery belt, has seen an increase in mob attacks on individuals and even killings.

Three months ago, a group of youths tortured five suspected witches before setting them on fire.

Al Jazeera's Mohammed Adow reports from Kisii.
