Catholic faithful in Venice react to Pope Francis' visit

Pope Francis travelled to the lagoon city of Venice on Sunday for a series of public appearances. The morning visit, which ended with Mass in St. Mark's Square, represented an increasingly rare outing for the 87-year-old pontiff, who has been hobbled by health and mobility problems that have ruled out any foreign trips so far this year.
