Former South African President Nelson Mandela's "health continues to improve but his condition remains serious", President Jacob Zuma has said.
After visiting Mr Mandela in hospital, Mr Zuma urged people to keep him "in their prayers".
The 94 year old is spending his sixth day in the Pretoria hospital suffering from a recurrent lung infection.
He became South Africa's first black president in 1994 after leading the struggle against white minority rule.
He stepped down five years later.
