Anti-apartheid hero Nelson Mandela has been placed on life support, as his health continued to decline.
The 94-year-old has been hospitalized since June 8 for a recurring lung infection.
Authorities described his condition as critical since Sunday, and President Jacob Zuma earlier on Wednesday said that Mandela's condition remained unchanged, and cancelled his trip to Mozambique where he was supposed to attend a summit on infrastructure investment.
South African government spokesman Mac Maharaj told CNN that officials were unable to comment on reports that Mandela was on life support, citing doctor-patient confidentiality rules.
In a statement issued late on Tuesday, the government said doctors continue to do their best to ensure Mandela's recovery, well-being and comfort, the report added.
