Nelson Mandela still critical in hospital, says Zuma

Former South African President Nelson Mandela remains in a critical condition in hospital, President Jacob Zuma says.

Mr Zuma said the doctors were doing everything they could to make the former leader comfortable, but he could not give any more medical details.

South Africa's first black president, 94, was taken to hospital in Pretoria earlier this month for the third time this year, with a lung infection.
