Pope Francis suffered two episodes of "acute respiratory insufficiency" on Monday, the Vatican said, a setback for the 88-year-old pontiff as he battles double pneumonia. Francis, who has been in Rome's Gemelli Hospital since February 14, is again receiving "non-invasive, mechanical ventilation" to help with his breathing.

Pope Francis, hospitalized for more than two weeks with pneumonia in both lungs, suffered two acute respiratory failures, requiring intervention, the Vatican says.
