The two black farmworkers accused of beating to death South Africa\'s white supremacist leader Eugene Terreblanche are due to go on trial shortly. Chris Mahlangu, 29, and a 16-year-old boy face charges including murder and robbery with aggravating circumstances. The pair handed themselves in to police after admitting they had clashed with their employer over pay. The 2010 killing highlighted South Africa\'s fragile race relations 16 years after white minority rule ended. When the pair were arrested, there were clashes between members of the local black community and Terreblanche\'s supporters in the north-western town of Ventersdorp, where the trial is due to start. Small groups from both sides have again gathered outside the court. Terreblanche had been stabbed and beaten with a wooden club. His Afrikaner Weerstandsbeweging (Afrikaner Resistance Movement - AWB) waged a violent campaign to resist the end of apartheid and the establishment of democratic rule in 1994. He spent three years in jail after the 2001 attempted murder of a farmworker. The trial has twice been postponed but both the defence and the prosecution say they are now ready to start, reports the South Africa Press Association.
