At least five people were killed in southern Malawi after they were accused of behaving like vampires.
According to reports, the victims were killed by vigilante mobs who suspected them of drinking human blood as part of magic rituals.
The UN said in a report that the vampirism rumours appear to have originated from Mozambique, and spread across the border to the Malawi districts of Mulanje and Phalombe.
It is unclear what sparked the fears, but – according to a UN report seen by news agency Reuters – villagers had set up road blocks as they tried to hunt the “vampires” down.
Malawian President Peter Mutharika has vowed to launch an investigation into the killings, with his office releasing an official statement saying the matter was “of grave concern” to the entire government”.
