Baku-APA. Mr Mandela, 94, has been in a Pretoria hospital since 8 June being treated for a recurring lung infection, and his condition became critical on Sunday, APA reports quoting BBC.
"Doctors continue to do their best to ensure his recovery, well-being and comfort," the latest update said.
The statement came as Mr Mandela's family members were meeting at his home in the village of Qunu.
His eldest daughter, Makaziwe, and some grandchildren were said to be at the meeting in Eastern Cape province.
Little has emerged from the family meeting, which South African media say was called to discuss "sensitive family business".
