Nelson Mandela's 'doing very well', says daughter

Nelson Mandela is "doing very well", one of his daughters, Zenani Mandela-Dlamini, has said.

Ms Mandela-Dlamini, South Africa's ambassador to Argentina, was speaking outside the Pretoria hospital treating the 94-year-old former president.

He has been in hospital for 10 days suffering from a lung infection.

Earlier, his wife Graça Machel issued a statement saying that messages of support the family has been sent from around the world have helped "lighten the burden of anxiety; bringing us love, comfort and hope".

Mrs Machel, the widowed Mozambican first lady who married Mr Mandela on his 80th birthday, said the family had been deluged with letters, text messages, phone calls, tweets, Facebook messages, emails, cards and flowers.

She added that "in particular, the voices of children in schools or singing outside our home" had brought the family great comfort.
