South African former President Nelson Mandela has been discharged from a hospital where he spent two nights.

Surgeon General Vejaynand Ramlakan said Mr Mandela, 92, was suffering from ailments that are common in people his age but was in good spirits.
Deputy President Kgalema Motlanthe - using Mr Mandela's clan name - said: "Madiba is well."
South Africa's liberation hero flew from Cape Town to Johannesburg on Wednesday for a check-up.
Friends and family visited him amid tight security at Milpark hospital on Thursday.
On Friday Mr Ramlakan said Mr Mandela had suffered a respiratory infection, but was responding well to treatment and would be receiving home-based care.
"To us he is stable, but will be subject to intense monitoring," he told reporters.
A convoy is now believed to be taking Mr Mandela to his home in the Johannesburg suburb of Houghton.
Correspondents say he has seemed increasingly frail since retiring from public life in 2004.
His last public appearance was at the football World Cup closing ceremony last July.

South Africa's revered former president Nelson Mandela was Thursday described as "very sick" but his condition was "not life-threatening."
The news that Madiba -- the clan name by which the 92-year-old Nobel Peace Prize winner and country's first elected black leader is affectionately known -- was to spend a second night in hospital has gripped the nation.
The public has grown increasingly concerned for Mandela's health but he could be released as early as today, a source close to Mandela said on condition of anonymity.
"The old man is very sick but his condition is not life threatening," the source said.
"He came in for a checkup but the doctor decided to keep him in for observation.
"He is still not well but we expect him to be released tomorrow."
President Jacob Zuma
described the hospital visit as a checkup and called for calm, but a report said Mandela had been treated for a lung problem.
Mandela spent 27 years in prison for his role in the fight against apartheid in South Africa, emerging in 1990 to lead the transition to democracy.
