JOHANNESBURG (AP) - South Africa's presidency says Mr Nelson Mandela has spent a night in the hospital after he was admitted for tests.
Presidential spokesman Mac Maharaj said on Sunday there were no updates on 94-year-old Mandela's condition since he went to a hospital in Pretoria on Saturday afternoon.
In a statement on Saturday, Mr Maharaj said the medical tests for the anti-apartheid leader and former president were scheduled and that doctors have indicated there is no cause for "alarm".
Mr Mandela was hospitalised for nearly three weeks in December before going home on Dec. 26. At that time, he was treated for a lung infection and had a surgical procedure to remove gallstones.
