Pope Francis, battling double pneumonia, remains in a critical condition for a second day running and his prognosis is still guarded, the Vatican said on Sunday. The pope, 88, was admitted to Rome's Gemelli hospital on February 14 after experiencing difficulty breathing for several days and subsequently had pneumonia diagnosed in both lungs.

The press office for the Vatican said Sunday that Pope Francis was able to rest overnight as he slowly recovers from double pneumonia after initially being hospitalized for bronchitis.

Pope Francis was in critical condition Saturday after he suffered a long asthmatic respiratory crisis that required high flows of oxygen, the Vatican said.
