Children from the Nonto Primary School in Soweto prepare to sing 'Happy Birthday' to former South African President Nelson Mandela at the ANC tree planted ceremony at Thokoza Park in Soweto Township.  The ANC hosted a tree planting ceremony at Thokoza Park in Soweto Township for Mandela Day on July 18, 2013 in Johannesburg, South Africa. The South African presidency has said that Mandela's health is 'steadily improving', as the anti-apartheid icon spends his 95th birthday in hospital. Photo: Charlie Shoemaker/Getty Images for Yahoo!
