Mandela enjoys 93rd birthday at home

Former President Nelson Mandela spent his 93rd birthday with friends and relatives in his rural hometown yesterday as South Africans paid tribute to the anti-apartheid icon through song and community service projects.

Millions of South African schoolchildren began their day by singing a special version of Happy Birthday to Mandela, leading a worldwide chorus of birthday wishes.

United States President Barack Obama called Mandela "a beacon for the global community, and for all who work for democracy, justice and reconciliation".

In 2009, the United Nations established Nelson Mandela International Day to honour the African leader on his birthday through acts of community service.

UN Secretary-General Ban Ki-moon urged people around the world "to make a difference" by tutoring a child, feeding the hungry or volunteering at a hospital or community centre.

"A healer of nations and a mentor to generations, Nelson Mandela - or Madiba as he is affectionately known by millions - is a living symbol of wisdom, courage and integrity," Ban said.

"Together, the best way we can thank Nelson Mandela for his work is by taking action for others and inspiring change."

South Africa's current President, Jacob Zuma, also paid a visit to Mandela in his home village of Qunu, about 1000km south of Johannesburg. Zuma spent more than two hours with the former President, before leaving with members of the Mandela family, including former wife Winnie Madikizela-Mandela.
