Necklacing

Necklacing is the practice of extrajudicial summary execution and torture carried out by forcing a rubber tire filled with petrol 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.
Necklacing was used by the black community to punish its members who were perceived as collaborators with the apartheid government. Necklacing was primarily used on black police informants; the practice was often carried out in the name of the struggle, although the executive body of the African National Congress (ANC), the most broadly supported South African opposition movement, condemned it. In 1986, Winnie Mandela, then-wife of the imprisoned Nelson Mandela, stated, "With our boxes of matches, and our necklaces, we shall liberate this country", which was widely seen as an explicit endorsement of necklacing. This caused the ANC to initially distance itself from her, although she later took on a number of official positions within the party.
The first victim of necklacing, according to the South African Truth and Reconciliation Commission, was a young black woman, Maki Skosana, on 20 July 1985.
Photojournalist Kevin Carter was the first to photograph a public execution by necklacing in South Africa in the mid-1980s. He later spoke of the images: 
He went on to say:

Some commentators have noted that the practice of necklacing served to escalate the levels of violence during the township wars of the 1980s and early 1990s as security force members became brutalized and afraid that they might fall victim to the practice.
Haiti.
This form of lynching is found in Haiti, where it was known as "Pé Lebrun", or "Père Lebrun" in French, after a tire advertisement showing a man with a tire around his neck. It was used prominently by mobs allied with Jean-Bertrand Aristide to assassinate political enemies. Aristide himself showed strong support for this practice, calling it "beautiful tool" that "smells good", encouraging his Lavalas supporters to use it against wealthy people as well as members of the Lavalas party who were not as strong in their fervor.
In other countries.
In the early years of the 1960s, when the seeds of the ethnic conflict in Sri Lanka (Sri Lankan Civil War) related to Eelam were being sown, Sinhalese rioters used necklacing in anti-Tamil riots. Necklacing was also widely used in the second armed insurrection led by the Janatha Vimukthi Peramuna. A graphic description of one such necklacing appears in the book "The Island of Blood" by journalist Anita Pratap.
In the early 1990s, university students in Abidjan, Ivory Coast, were plagued by burglars stealing from their dormitories. The students took matters into their own hands by capturing the alleged thieves, and then executed them by placing tyres around their necks and setting the tyres on fire. Ivorian police, powerless to stop these necklacings, could do nothing but stand by and watch.
In 2006, at least one person died in Nigeria by necklacing in the deadly Muslim protests over satirical cartoon drawings of Muhammad.
The practice is widely used by drug dealers in Brazil, notably in Rio de Janeiro, where it is called "micro-ondas," or "microwave" in Portuguese. Journalist Tim Lopes was a notable victim.
