SCIUTTO: A very Merry Christmas to you, your family, to all our servicemen and women serving both here in the U.S. and far from home. Christmas celebrations happening around the world this hour, it's a time of peace, reflection for Christians honoring the birth of Jesus. This morning, Pope Francis hosted a Christmas mass at the Vatican. Later, his message delivered to St. Peter's square, he encouraged the faithful to denounce materialism and selfishness. He also wished for this, quote, "fraternity among individuals of every nation and culture." There were smiles on the faces of migrant children off the coast of Libya. These children rescued in the Mediterranean Sea. Rescuers provided the children with toys and games and even Santa hats there, as you can see. In China, the small Catholic population there celebrating mass. Tibetan Catholics also marking the day with traditional dancing and cakes. And a festive but very chilly celebration in Germany, the Berlin Seal swimmers took their traditional dip in a lake. The temperature, a cool 39 degrees Fahrenheit, ouch. But the Christmas cheer is surely keeping them warm this winter. There is much more ahead on CNN. A very Merry Christmas to you. Thanks so much for joining us. I'm Jim Sciutto. "At This Hour" with Kate Bolduan will be right back after a quick break.
