Former South African president Nelson Mandela was comfortable in hospital on Saturday after undergoing a diagnostic procedure for abdominal pains, the government said, telling people not to panic about the health of the 93-year-old anti-apartheid leader.
A statement from President Jacob Zuma said Mandela, who is popularly known by his clan name, Madiba, should be discharged on Sunday or Monday after being checked out for a long-standing abdominal complaint.
Madiba is fine and fully conscious and the doctors are satisfied with his condition, which they say is consistent with his age, it said.
He was in good health before admission in hospital but doctors felt the complaint needed a thorough investigation.
We are happy that he is not in any danger and thank the doctors for their hard work and professionalism.
Although short on medical details, the openness and speed of the government response stood in contrast to a year ago when Mandela was admitted to hospital with respiratory problems.
Then, Zuma's office took hours to confirm media reports of his declining health, leading to a scrum of local and international reporters outside Johannesburg's Milpark hospital.
The government has not said where Mandela is, although security has been tightened at Pretoria's 1 Military hospital, which is officially responsible for the health of sitting and former presidents.
Amid earlier unconfirmed reports that Mandela was undergoing a hernia operation, a spokesman for the ruling Africa National Congress (ANC) went on television to tell South Africa's 50 million people there was nothing to worry about.
There's no need for panic, ANC spokesman Keith Khoza told the e-News channel. It was not an emergency admission. It was planned.
Mandela has been in poor health since his hospitalisation a year ago, and has not appeared in public since. He has spent his time at his home in Johannesburg's northern suburbs and his ancestral village of Qunu in the impoverished Eastern Cape.
As South Africa's first black president, Mandela occupies a central position in the psyche of a country that was ruled by the 10 percent white minority until the first all-race elections in 1994.
Earlier this month, Zuma and the central bank issued a new set of bank notes bearing his image.
However, he has long since withdrawn from active participation in politics and public life in Africa's biggest economy, having stood down at the end of his first term in office in 1999.
His last major public appearance was in July 2010 at the final of the World Cup in Johannesburg's Soccer City stadium.
