Nelson Mandela Much Better Today - Jacob Zuma

South African President Jacob Zuma says that Nelson Mandela's condition has improved, but still remains critical.

"He is much better today than he was when I saw him last night," Mr Zuma said after speaking to the 94-year-old's medical team.

South Africa's first black president an icon of the anti-apartheid struggle has been in hospital in Pretoria since 8 June with a lung infection.

Mr Zuma cancelled a visit to Mozambique to visit Mr Mandela in hospital.

Meanwhile Mr Mandela's daughter Makaziwe said he was "still there" and responding to touch.

US President Barack Obama, who is in Senegal, described Mr Mandela as "a hero for the world".

"His legacy will linger on through the ages," he said.
