US President Barack Obama has paid tribute to Nelson Mandela at a huge memorial service in Johannesburg's FNB stadium.
Mr Obama said the former South African leader, who led the transition from white minority rule in his country, had lived "a life like no other" and "moved billions around the world".
He also praised Mr Mandela's commitment to democracy and willingness to step down from power after just one term.
