Zindzi Mandela, daughter of South African anti-apartheid icons Nelson and Winne Mandela, has died in Johannesburg at the age of 59. State broadcaster SABC said Mandela died at a hospital in the South African capital, but did not reveal a cause of death.  Her death was confirmed by the ruling African National Congress, which her father led in the struggle against South Africa’s white minority-ruled apartheid regime, then as the country’s first Black president.   FILE – A 1990 photo showing Nelson Mandela and his then wife Winnie walking upon his release from Victor prison, Cape Town, South Africa.Zindzi rose to prominence in 1985 when she read a letter from her father rejecting then-President P.W.

She served South Africa well.”
