Former South Africa President and anti-apartheid hero Nelson Mandela spent a second night at military hospital here on Sunday and a government statement said he was "comfortable".
The country´s President Jacob Zuma visited him at the hospital and reports quoted him as saying the he found Mandela "comfortable, and in good care".
The government refused to divulge the exact reason for which the 94-year-old leader was being treated. All it said was that he was undergoing some medical tests "consistent with his age".
This is the second time he has been admitted to a hospital this year.
Madiba, as he is affectionately known by South Africans, has retired from public life and lives in his childhood hometown of Qunu in the rural Eastern Cape.
