The continued uncertainty about Mandela's health saw worshipers gather Sunday morning at the Regina Mundi Catholic church in the Soweto area of Johannesburg to pray for the leader. The church was a center of anti-apartheid protests and funerals.
"Yes, it really worries us because he is a great person," church goer Shainet Mnkomo said as she left an early morning service. "He did so many things to the country, he's one of those persons who we remember most."
Mandela, who spent 27 years in prison for fighting racist white rule, became South Africa's first black president in 1994 and served one five-year term. He later retired from public life to live in his remote village of Qunu, in the Eastern Cape area, and last made a public appearance when his country hosted the 2010 World Cup soccer tournament.
Many in this country of 50 million people view Mandela, who led the African National Congress to power, as a father figure and an icon of integrity and magnanimity amid the nation's increasingly messy politics.
