A disturbing video has emerged that appears to show four women being tortured by a gang of men after being accused of witchcraft.

The footage was reportedly taken in a village in Papua New Guinea, a country where violence and murders linked to sorcery are rife.

The women were accused of sorcery after a young man fell ill. Villagers claimed the women had 'invisibly' taken out the man's heart.

In the video, the women have been stripped naked, tied up, burned and beaten. It also shows them
being threatened with machetes while being questioned by the men.

The suspects repeatedly deny the allegations, with one woman begging her attackers: 'My son, stop it!'
A man replies: 'Talk out, where did you put it? Burn her with the wire.'
Another woman says: 'I've got nothing to do with it,' says another woman. 'I am a mother with five children.'

The gang later claimed the women returned the man's heart after they were tortured, apparently proving their guilt, according to the social media reports. It is believed at least one woman died after the ordeal, but this has not been confirmed.
