Mandela Memorial

The official memorial for former president Nelson Mandela is being held at FNB Stadium in Soweto today.

Nearly 100 heads of state and tens of thousands of people have packed into the stadium for the four-hour service to pay tribute to the late statesman.

When US President Barack Obama took to the stage at a soaked FNB Stadium this afternoon, his speech brought both world leaders and ordinary South Africans to their feet.
