Nelson Mandela showing 'great resilience' in hospital

Nelson Mandela is reportedly showing "great resilience" although "at times, his condition becomes unstable," according to a statement from the South African president's office.

"Doctors are still working hard to effect a turnaround and a further improvement in his health and to keep the former president comfortable," the statement added.

The BBC confirmed the assessment coincides with comments from members of Mandela's family who have been visiting him over the past few weeks.

It was the first update in almost two weeks on Mandela's health.
