Nelson Mandela improvement sustained, says Jacob Zuma

Former South African President Nelson Mandela continues to get better in a Pretoria hospital, current President Jacob Zuma has said.

He added that the revered ex-leader remained in a serious condition as he recovered from a lung infection.

"Over the last two days, although he remains serious, his doctors have stated that his improvement has been sustained," Mr Zuma said.

He added that Mr Mandela "continues to engage with family".
