Nelson Mandela's former wife grieved for him in public today at a memorial service for South Africa's first black leader.
Dressed in black, Winnie Madikizela-Mandela attended a Methodist service in the northern Johannesburg suburb of Bryanston, where President Jacob Zuma hailed the values of the country's most beloved statesman.
'He believed in forgiveness and he forgave, even those who kept him in jail for 27 years,' Zuma said in a eulogy. 'He stood for freedom. He fought against those who oppressed others. He wanted everyone to be free.'
The service was held as the country started a week of mourning for the inspirational freedom fighter. South Africa is readying itself for the arrival of a flood of world leaders for Mr Mandela's memorial service and funeral.
People are gathering all across South Africa today as Nelson Mandela's 'Rainbow Nation' starts a week of official mourning to mark his death.
The country has come to a standstill for a national day of reflection as people mass together in parks, churches and public spaces to pay tribute to South Africa's first black president.
Mr Mandela, also known as Madiba, passed away on Thursday at his home in Houghton at the age of 95. It provoked a worldwide outpouring of emotion.
