Syrian refugees waves and smiles upon their arrival at Rome's Fiumicino international airport, Monday, Feb. 29, 2016. They landed at Rome's Leonardo Da Vinci airport thanks to the "humanitarian corridor" project launched by the Rome-based Catholic Sant'Egidio Community and the Federation of Protestant Churches in Italy. Speaking to people in St. Peter's Square Sunday, Pope Francis said a "concerted response can be more effective and distribute equally the weight" of helping the migrants.
