Terrorists in Iraq have stepped up attacks against the country's minority Christian population. An attack against a Christian church in Baghdad on 31 October, left 58 worshippers dead including two priests. It was one of the worst in the spate of attacks that have targeted Iraqi Christians and have left scores dead.
There have been calls for Iraq to create an autonomous Christian region in the north of the country, where around 100,000 Christians have taken refuge since the US-led invasion and occupation of Iraq in 2003.Many of Iraq's approximately 500,000 remaining Christians are said to be living in fear of their lives.
Christians and other religious minorities make up less than 5 percent of Iraq's population, according to the U.N. High Commissioner for Refugees.
