South African ex-President Nelson Mandela is spending a fourth day in a Pretoria hospital where he is being treated for a recurrent lung infection.
The office of President Jacob Zuma says the 94 year old remains in a serious but stable condition.
Relatives, including his ex-wife Winnie Madikizela-Mandela, visited the ailing former leader on Monday.
