South Africa will not send black leader Nelson Mandela back to prison when he completes his hospital stay but will keep him under guard at an unspecified location. A brief statement on Thursday by Justice Minister Kobie Coetsee did not give any details on when Mandela would leave the hospital, where he would be taken, or what restrictions he would face. Mandela, head of the African National Congress guerrilla movement, has been recovering from tuberculosis since August.
