She was also highly critical of the behaviour of the international media.
There is a racist element with many of the international media where they cross boundaries truly vultures waiting for when the lion has devoured the buffalo it has gone overboard Ms Mandela said.
Mr Zuma's spokesman Mac Maharaj said on Wednesday evening that Mr Mandela's condition had deteriorated over the weekend.
