JOHANNESBURG (AP) - South Africa says Nelson Mandela has been admitted to a hospital with a lung infection. The office of President Jacob Zuma said in a statement Thursday that the 94-year-old former president and anti-apartheid leader went to the hospital just before midnight on Wednesday. The statement says Mandela is being treated for a "recurrence of his lung infection" and that doctors are ensuring he has the best possible treatment. Zuma wished Mandela a speedy recovery and he urged South Africans and the world to pray for the former leader and his family. Mandela has become increasingly frail in recent years.
