FORMER Zambian President Kenneth Kaunda’s son and political heir-apparent, Wezi, was buried in Lusaka on Tuesday. He was slain nearly a week ago by gunmen whose motives remain unclear. Tears streamed from many, including the 76-year-old statesman who ruled Zambia from 1964 to 1991. Wezi, a retired army major, was on the point of running for office in Kaunda’s opposition United National Independence Party when four men last Wednesday seized his car, inflicting fatal gunshot wounds before fleeing. Police suspect it was a carjacking and have arrested two men. But Kaunda says he fears it was a political assassination, possibly contrived by dissident UNIP members in league with President Frederick Chiluba’s ruling Movement for Multiparty Democracy. South Africa has granted political asylum since the shooting to Kaunda’s daughter Catherine.
