By Stella Mapenzauswa and David Dolan JOHANNESBURG (Reuters) - World leaders from U.S. President Barack Obama to Cuba's Raul Castro joined thousands of South Africans to honour Nelson Mandela on Tuesday in a memorial that will celebrate his gift for uniting enemies across political and racial divides. Obama and former president George W. Bush and their wives Michelle and Laura arrived from Pretoria's Waterkloof air base as singing, dancing South Africans made their way through heavy rain to Johannesburg's Soccer City where the homage to Mandela will be held. Obama and Castro, whose nations have been foes for more than half a century, are among the designated speakers at the stadium where 23 years earlier Mandela, newly freed from apartheid jail, was hailed by supporters as the hope of a new South Africa. Since Mandela's death, Johannesburg has been blanketed in unseasonal cloud and rain - a sign, according to African tradition, of an esteemed elder passing on and being welcomed into the afterlife by his ancestors.
Soweto (South Africa) (AFP) - 0857 GMT: A marching band emerges into the stadium to roars and chants from the crowd, which is chanting and singing in a party atmosphere. 0852 GMT: Francois Pienaar, the South Africa rugby captain of the side which won the 1995 World Cup on home soil, receiving the trophy from Mandela, has been speaking to journalists. "The legacy of Mr Mandela is in the hands of the young ones," he said, encouraging young people to vote in the key general election next year. The story of Pienaar and the rest of the Springboks' extraordinary relationship with Mandela is told in the Hollywood film "Invictus" featuring Matt Damon as the rugby star.
