Former South African President Nelson Mandela has been hospitalized again, but officials say it's only for a routine checkup. "Doctors are conducting tests and have thus far indicated that there is no reason for any alarm," according to a statement from the presidential office Saturday. In January, Mandela completed his recovery from a lung infection and gallstone surgery and gradually returned to his normal routine, officials said at the time. Mandela, 94, who has not appeared in public since 2010, had continued receiving treatment at his home in Houghton, a suburb of Johannesburg, according to a report of CNN.
