Pope Francis has demanded Europe craft a unified and fair immigration policy, saying the thousands of refugees coming ashore need acceptance and assistance, not self-interested policies that risk lives and fuel social conflict. Francis made the comments Tuesday to the European Parliament during a brief visit meant to highlight his vision for Europe a quarter-century after St. John Paul II travelled to Strasbourg to address a continent still divided by the Iron Curtain.
