Mourners watch U.S. President Barack Obama addressing the crowd during the national memorial service for late former South African President Nelson Mandela in Johannesburg's National Bank Stadium December 10, 2013. More than 70 world leaders from U.S. President Barack Obama to Iran's Hassan Rouhani are flying to South Africa for events commemorating Mandela this week, an unprecedented gathering that will hail one of humanity's great peacemakers. The 95,000-seat stadium in Soweto, the township that was at the heart of the anti-apartheid struggle, will host the main memorial ceremony for Mandela, who died on December 5 aged 95.
