ROME — Pope Francis rested early Tuesday after he suffered further setbacks in his fight against double pneumonia: two new acute respiratory crises that required him to resume using noninvasive mechanical ventilation to breathe. In its early Tuesday update, the Vatican said: “The pope slept through the night, now rest continues.”

Pope Francis experienced more respiratory problems and went on noninvasive ventilation on Monday, the Vatican said, as the head of the Roman Catholic Church battles double pneumonia in the hospital.
