Iraq's dwindling Christian community faces "disaster," and if ** action is taken they will number just a few thousand in a decade, the country's most senior church leader told AFP. Chaldean Patriarch Louis Sako said the daily migration of Christians from Iraq was "terrifying" and blamed a range of factors, including generally poor security in the country and worsening religious extremism. Iraq's Christian community is a shadow of what it used to be -- once numbering more than a million nationwide, with upwards of 600,000 in Baghdad alone, there are **w fewer than 400,000 across the country. "The daily migration of Christians from Iraq is terrifying and very worrying," Sako told AFP from the ethnically-mixed **rthern city of Kirkuk on Friday evening.
