JOHANNESBURG - Former South African President Nelson Mandela remains in a hospital Sunday while he receives treatment for a recurrence of pneumonia.

South African presidential spokesman Mac Maharaj says there are no updates on 94-year-old Mandela since an official statement Saturday on his condition. That statement reported the anti-apartheid leader was breathing without difficulty after having a procedure to clear fluid in his lung area.

Mandela was admitted to a hospital in the capital, Pretoria, near midnight Wednesday. It was his third trip to a hospital since December, when he was treated for a lung infection and also had a procedure to remove gallstones. Earlier in March, he spent a night in a hospital for what officials said was a scheduled medical test.
