Former South African leader Nelson Mandela has been admitted to hospital to undergo tests, according to the country's president, Jacob Zuma.
The 94-year-old's visit to hospital was "no cause for alarm", the president's office said on Saturday.
"Former President Mandela will receive medical attention from time to time which is consistent with his age," the statement said.
"President Zuma assures all that [Mandela] is doing well and there is no cause for alarm."
South Africa's first black president and a Nobel Peace Prize winner, Mandela has previously been treated in hospital for a serious chest infection in 2011, and also for an abdominal problem earlier this year.
Mandela, who was the leading figure in the anti-Apartheid movement in the country, spent 24 years in Robben Island prison in the country, before
Mandela retired from public life in 2004.
