Pope Francis, who has been hospitalized for over a week, is in critical condition after a "prolonged asthma-like respiratory crisis," the Vatican said Saturday. The pope is "more unwell than yesterday," the Vatican said in a statement.

The Vatican says Pope Francis is in critical condition after he suffered a long asthmatic respiratory crisis that required high flows of oxygen.

Doctors on Friday said the 88-year-old Francis is "not out of danger" ​and that the main threat facing him would be the onset of sepsis.
