Necklacing
Necklacing is the practice of summary execution and torture carried out by forcing a rubber tire, filled with gasoline, around a victim's chest and arms, and setting it on fire. The victim may take up to 20 minutes to die, suffering severe burns in the process.
In South Africa
The practice appears to have begun in the Eastern Cape area of South Africa in the mid-1980s. One incident sometimes cited as the first recorded instance of necklacing took place in Uitenhage on 23 March 1985 when a group of people killed Benjamin Kinikini, a local councillor who was believed to be involved in violence and corruption and having links to a vigilante group. Kinikini and members of his family were dragged out of their house, stabbed to death, and their bodies set on fire. Two of those judged to be the perpetrators, Wellington Mielies, 26, and Moses Jantjies, 23, were hanged on 1 September 1987. But in this case the victims were killed by stabbing, and not by burning tires.
Something similar seems to have happened in the killing of Matthew Goniwe and his fellow anti-apartheid activists by the police in July 1985.
