Eleven people accused of being witches have been burned to death by a mob in the west of Kenya, police say.
A security operation has been launched to hunt down villagers suspected of killing them in Kisii District.
The area has witnessed similar attacks in the past when people suspected of engaging in witchcraft have been killed or ostracised.
But correspondents say that this is a surprisingly large number of people to be attacked at the same time.
The BBC's Muliro Telewa in the region says that the eight women and three men were not burned at the same time.
A list was used and villagers pulled them from their houses individually, attacked and burned them outside and then set their homes alight.
Villagers told reporters that they had evidence the victims, all aged over 80, were witches.
They say they found an exercise book at a local primary school that contained the minutes of a "witches' meeting" which detailed who was going to be bewitched next.
Local official Mwangi Ngunyi condemned the murders.
"People must not take the law into their own hands simply because they suspect someone," he told AFP news agency.
