South African anti-apartheid writer Andre Brink, 79, died on Friday after suffering a blood clot while on a plane to Cape Town from a Belgian University where he was collecting an honorary doctorate, local media said. Brink, who wrote in English and Afrikaans, was a leading member of the Sestigers, a group of influential Afrikaans writers in the 1960s who opposed the apartheid government. Brink, who was also a playwright and an academic, was an English professor at the University of Cape Town when he died.
