Pope Francis, battling double pneumonia, remains in a critical condition and his prognosis is still guarded because of the "complexity" of his clinical condition, the Vatican said on Sunday.

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.

Francis remains in critical condition but has not suffered any additional crises, the Vatican said Sunday evening, after reporting Saturday the pope suffered a “long asthmatic respiratory crisis” days after he was hospitalized for pneumonia.
