The wife of critically ill Nelson Mandela says the former South African president is sometimes uncomfortable but seldom in pain while being treated in a hospital.

Graca Machel spoke about her husband's condition on Thursday at a fundraising drive for a children's hospital that will be named after the 94-year-old anti-apartheid leader.

A Mandela family court affidavit obtained by the Mail and Guardian newspaper said Mandela is on life support in the form of a breathing respirator.

Also, the office of President Jacob Zuma said he visited Mandela on Thursday. Zuma's office says Mandela, who was hospitalized on June 8, remains in critical but stable condition.

Mandela was imprisoned for 27 years during white racist rule and was freed in 1990 before being elected president in all-race elections.
