South Africa's former leader Nelson Mandela has been admitted to hospital in the capital Pretoria to undergo tests, officials say.
The office of President Jacob Zuma said 94-year-old Mr Mandela was doing well and there was "no cause for alarm".
Mr Mandela spent more than two decades in jail under the white-minority apartheid regime.
He served as South Africa's first black president between 1994 and 1999, and received the Nobel Peace Prize in 1993.
