Nelson Mandela's health has worsened over the past twenty four hours, according to a statement released by the South African President Jacob Zuma on Sunday.
After days of health reports stating that Mandela was in a "critical but stable" condition, the South African president revealed that his condition was deteriorating.
President Zuma said that the former South African president and Nobel Peace Prize Laureate was "in good hands," and added that the doctors were doing everything possible to improve his health.
"The doctors are doing everything possible to get his condition to improve and are ensuring that Madiba is well-looked after and is comfortable. He is in good hands," said the South African president, using Mandela's clan name by which he is widely known in the country.
Mandela was hospitalized in Pretoria earlier this month with lung infection. This is his third hospitalization in the last six months.
Nelson Mandela is widely revered for his leading role in South Africa's fight against the white minority rule in the country. He is a popular figure and beloved of his countrymen and news about his worsening condition could alarm the whole nation.
President Jacob Zuma's spokesman Mac Maharaj said that the doctors' use of the word "critical" was "sufficient explanation that should raise concern amongst us", reports BBC.
"Therefore we want to assure the public that the doctors are working away to try and get his condition to improve," said the spokesman, appealing to the public to keep clam and hope for the best.
The White House on Sunday issued a statement of support and prayers for the family members of ailing Mandela and the people of South Africa as well.
"Our thoughts and prayers are with him [Mr Mandela], his family and the people of South Africa," said the statement from the White House.
