His public appearances are increasingly rare.<br /> </p><p><br /> A private burial was held earlier, with public welcomed to the chapel service. Several hundred people attended, including an overflow crowd in a tent outside, where they could listen to the service.<br /> </p><p><br /> Zenani's classmates in school blazers and other mourners each held a single white rose.
