A South African government minister has told a special prayer service for Nelson Mandela that, as the former president is lying in hospital critically ill, he is "uniting the nation without even saying a word.''

Melusi Gigaba, the Minister of Public Enterprises, was addressing a congregation of several hundred people at a church in Katlehong, to the east of Johannesburg.
