They are attacked and massacred, driven into exile from a region in which their presence has always been essential.

In his Christmas message, the Archbishop says: "Christmas means that, through Jesus, God shows unconditionally that he loves us. I pray that he gives you a very blessed Christmas."

We pray for his family, for his friends and for his country.
We are challenged to show the same degree of humanity, of courage and of generosity.

Jackie Perry blamed advertising: "What do you expect when children and adults alike are bombarded with media hype and having Christmas adverts rammed down their throats from October."
But Nicola Bulloc said: "I am on a low wage but I always manage to buy all the presents and bits without getting in debt."
