(ANSA) - Papal Flight, September 28 - Pope Francis told reporters on the papal flight back to Rome on Monday that migrant barriers like those erected by Hungary on its border with Serbia will not last. "You know how walls finish up," Francis said. "All walls collapse - today, tomorrow or after 100 years. Walls are not the solution. The problem remains, but with more hate". http://popefrancisnewsapp.com/
