Mandela: Tributes mount up outside hospital

Tributes are mounting outside the Pretoria hospital where former president Nelson Mandela is being treated for a recurring lung infection.

Many South Africans, including young children, have left pictures, poems and other items on the fence outside the hospital.

Mr Mandela's medical condition was described as critical on Sunday, and the South African government have said his condition remains unchanged.
