In Pictures: Christmas celebrations around the world
Worshippers gathered at churches for midnight mass and other services while some chose to take a festive dip to mark the holiday.

In Ukraine the ongoing conflict with Russia also cast a shadow although many Christians in both countries celebrate Christmas in January.
