Johannesburg, South Africa -- The office of South Africa's president says former leader Nelson Mandela has been taken to a hospital because of a lung infection.
A statement from President Jacob Zuma's office says Mandela had a recurrence of the illness in the last few days, and that he was transferred to a Pretoria hospital after his condition deteriorated at about 1:30 a.m. on Saturday.
The statement says Mandela, who is 94 years old, is in "serious but stable" condition and is receiving expert medical care.
The anti-apartheid leader became president in South Africa's all-race elections in 1994. His health has been failing in recent years.
