All-night prayers and songs for Nelson Mandela

South Africans have been holding all-night prayer vigils for former President Nelson Mandela at the hospital where he is being treated, and outside his former home in Soweto.

The crowds have been singing and saying prayers for Mr Mandela's health, on what is now his 20th night in hospital in Pretoria.

South Africa's first black president - an icon of the anti-apartheid struggle - is suffering from a lung infection.
