Mandela marks 20 years of freedom

South Africans are celebrating how far they have come since Nelson Mandela took his first steps to freedom 20 years ago today.

Thousands gathered for commemorations at what was known in 1990 as Victor Verster Prison, near Cape Town. A re-enactment is planned of the moment Mandela, hand-in-hand with his then-wife Winnie, walked free after 27 years in prison.
