Nelson Mandela remains 'critical but stable'
Nelson Mandela's condition is "improving" according to former South African President Thabo Mbeki, but a family member says his condition remains "critical but stable.''
The former leader's grandson, Ndaba Mandela, said he is responding during visits.
Earlier this week, President Jacob Zuma said the 94-year-old remained "critical but stable" in a Pretoria hospital.
