Pope Francis' health improves, with Vatican sources saying his condition not currently critical

Pope Francis' health has improved, Vatican sources indicated to CBS News on Friday, saying he was not currently in critical condition after exactly two weeks in hospital for bronchitis that developed into pneumonia in both lungs.

"The clinical picture remains complex, the criticality has subsided for the moment, but I would respect the caution of the doctors as the prognosis remains guarded," the sources said. There was no indication of how much longer the pontiff might remain hospitalized.

The Vatican has been providing brief updates on the 88-year-old pope's health twice daily, and he had been improving in recent days, but doctors said his condition remained critical until Friday.
