ROME (AP) — Pope Francis continued to improve from double pneumonia Thursday, the Vatican said, working from his hospital room and going to his private chapel to pray, though doctors said he needs more days of “clinical stability” before they revise their guarded prognosis.

As pilgrims and other well-wishers continue to gather to pray and leave offerings outside the hospital, medical experts - together with the Vatican - have warned that Francis is not out of danger.

Pope Francis' condition continued to improve on Thursday, with the pontiff alternating between high-flow oxygen therapy and ventimask, according to the Vatican.
