A life lived in fear: the cross that Iraq's Christians have to bear

Christians have marked All Saints Day by mourning the churchgoers killed in Iraq on Sunday. Al-Qaeda claimed responsibility for the attack, which saw gunmen take worshippers hostage at Baghdad's Our Lady of Salvation church. The stand-off which followed claimed more than 50 lives, and highlighted the danger that Iraqi Christians have lived in, or have fled from, over the last 7 years.
