““Iraq's Christian communities date back to the first centuries of the religion. Before the 2003 U.S-led invasion, around 1 million Christians called Iraq home. But since then, the community has been a frequent target for militants. Attacks on churches, worshipers and clergymen have prompted many Christians to leave the country. Church officials now estimate the community at around 450,000. The prime minister, who has ruled the country since 2006, is under pressure to step aside and not seek a third consecutive term. Many in Iraq accuse al-Maliki's Shiite-led government of helping fuel the crisis by failing to promote reconciliation with the Sunni Muslim minority, and say he has become too polarizing a figure to unite the country and face down the militant threat.””
