South Africa's presidency says it has no updates on the condition of former leader Nelson Mandela, who is convalescing at home after a hospital stay and is reported to be doing better.

The South African Press Association quotes presidential spokesman Mac Maharaj as saying Saturday that he has no new information on 94-year-old Mandela, who was released from a hospital on Wednesday. The former president, who spent 27 years in prison under apartheid, was admitted Dec. 8 and received treatment for a lung infection.

He also had a procedure to remove gallstones.

Maharaj previously said doctors have noted progress in Mandela's condition but will continue to treat him at his home in the Johannesburg neighborhood of Houghton.
