Mandela in hospital for check up

Former South African President Nelson Mandela has been admitted to hospital for a scheduled check-up, the South African presidency says.
Doctors are conducting tests and have so far indicated that there is no reason for any alarm, the presidency said on its website.
The 94-year-old spent 18 days in hospital in December.
He was treated for a lung infection and gallstones. His health has been a cause of concern for many years.
The message posted by President Jacob Zuma’s office said Mr Mandela had been admitted for a check-up at a Pretoria hospital this afternoon.
It said the aim was “to manage existing conditions in line with his age”.
