White South African farmers and rival Black protesters hurled abuse and threats at each other on Friday ahead of a court hearing in a murder case that has exposed still simmering racial tensions 26 years after the end of apartheid. The killing of Brendan Horner, a white man whose body was found tied to a pole at his farm in Free State province, sparked riots at the start of this month, and prompted President Cyril Ramaphosa to make a statement urging South Africans to “resist attempts… to mobilise communities along racial lines”. The farmers, who accuse the government of failing to protect them from violent crime, arrived in pick-up trucks ahead of the court hearing in the central town of Senekal for Horner’s two suspected killers.
