Pope Francis has cancelled his official audiences for Monday due to a "slight flu-like state," the Vatican announced. This comes just days before his planned trip to Belgium and Luxembourg and was described as a precautionary measure by Vatican officials. The 87-year-old pontiff is scheduled to visit Luxembourg on Thursday, followed by a visit to Belgium, culminating in a Mass in Brussels on Sunday. The trip comes on the heels of an extensive 11-day, four-nation tour of Asia that the pope returned from on September 13. (This story was generated by Newser's AI chatbot. Source: the AP)
