Children sing to celebrate Nelson Mandela's birthday
Children in South Africa have been marking Nelson Mandela's 95th birthday with celebrations and song.
Mr Mandela is in hospital in Pretoria, where he is in a critical but stable condition with a recurring lung infection.
South Africans are being urged to mark the former president and anti-apartheid leader's 67 years of public service with 67 minutes of charitable acts.
President Jacob Zuma said his health was "steadily improving".
