Some of the 20 right-wing extremists convicted of high treason for a plot to kill former South African President Nelson Mandela. One of the plots involved trying to use a landmine to kill Mr Mandela, the country's first black president. It was foiled after Mr Mandela arrived at the location, a school, by helicopter. Relatives of right-wing extremists, convicted of high treason for a plot to kill former South African president Nelson Mandela, react following the verdict. Emotional family members leave the courthouse after members of the right-wing "Boeremag" were sentenced at Pretoria High Court over a plot to assassinate Nelson Mandela. Right-wing groups bussed in a small number of supporters to the court in Pretoria to support those being sentenced. The court is the same one where Mr Mandela and other anti-Apartheid activists were convicted of treason in 1964.
