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.

Pope Francis, who has been hospitalized for more than a week, had a peaceful night which “passed quietly” after suffering from a respiratory crisis on Saturday, the Holy See Press Office said Sunday morning.
