The condition of Nelson Mandela remains unchanged, with doctors describing it as "serious but stable".
The former South African president and anti-apartheid hero is being treated in hospital for a lung infection. The 94-year-old was admitted to a Pretoria hospital in the early hours of Saturday.
It is his 4th hospital stay since December. He had spent 10 days in hospital between March and April to receive treatment for pneumonia.
"President Jacob Zuma reiterates his call for South Africa to pray for Madiba and the family during this time," the government said yesterday.
Mandela has not been seen in public since 2010, but remains a towering symbol in South African public life. On Sunday, members of his family were seen visiting the hospital where he is believed to be staying.
Mr. Mandela has a history of lung problems dating from when he contracted tuberculosis as a political prisoner. He spent 27 years on Robben Island and in other jails for his attempts to overthrow the white-minority government.
After becoming South Africa's first black president in 1994, he stepped down as president in 1999 and has not been politically active for a decade.
His last major public appearance was in July 2010, at the final of the FIFA World Cup at Soccer City stadium in Johannesburg.
