Pope Francis referred to an "Arab invasion" during a speech to a French Christian group this week, adding that Europe has been enhanced by previous influxes of people.
The pontiff also noted that Europe has seen many invasions over the course of its history, according to excerpts of the comments posted on the website of the Vatican newspaper L'Osservatore Romano.
