Christians around the world celebrated Christmas on December 25th, marking the birth of Jesus. One of those celebrations, which you see right here, was held in the city of Bethlehem, the site where Jesus was born. Worshippers gathered at the Church of the Nativity for a ceremony there.And at the Vatican, Pope Benedict XVI led the traditional Christmas Eve Mass. There was a disruption at the beginning, though, when a woman ran toward the pope and knocked him down. The religious leader wasn't hurt. He was helped up and continued with the ceremony, while Vatican guards removed the woman.
