Former President Nelson Mandela's wife Graca Machel on Monday thanked everyone who had sent messages of support for the ailing icon.
"So much love and generosity from South Africans, Africans across the continent, and thousands more from across the world, have come our way to lighten the burden of anxiety, bringing us love, comfort and hope," Machel said in a statement.
Machel said the family's gratitude was difficult to express.
Mandela, 94, was spending his tenth day in hospital on Monday.

stable" condition.
