JOHANNESBURG: South Africa prayed for Nelson Mandela yesterday as the revered peace icon faced a third night in hospital, with calls for the family and the nation to "let him go". Government officials had given no update on Mandela's health since announcing that the 94-year-old was admitted early Saturday and was in a "serious but stable" condition with a lung infection. "I've seen my father and he's well. He's a fighter," his daughter Zindzi told The Guardian newspaper on Sunday.
