Mandela memorial: 'Giant of history' honoured

Tens of thousands of South Africans have joined dozens of world leaders for the national memorial service for former President Nelson Mandela.

The service was held in front of a vociferous crowd in the FNB stadium in Johannesburg.

Among those paying tribute to Mr Mandela were US President Barack Obama, Cuba's Raul Castro and UN Secretary General Ban Ki-moon.
