Pope Francis has urged the world not to ignore the plight of millions of migrants "driven from their land", during Christmas.

He compared them to Mary and Joseph, recounting the Biblical story how they had to travel from Nazareth to Bethlehem but found no place to stay.

Many migrants, he said, were being forced to flee from leaders who "see no problem in shedding innocent blood".

The leader of the world's estimated 1.2bn Roman Catholics also stressed that faith demanded that foreigners be welcomed everywhere.

His comments come as the number of refugees worldwide exceeds 22 million.
