The statement from the nunciature points out that Christians have often been targets, and especially the Christians of Mosul "have paid a high price, despite their unanimously recognized peaceful life."
Eight Christians have been killed in that city in just 10 days.
"One has the impression that the reason to attack these minorities is strictly and only their religious faith or their different ethnic membership," the nunciature note continues. "Many Christians live in fear of staying in the territory which has seen them present for 2,000 years.
"Someone is trampling on their indisputable right to full citizenship, driving them with the force of violence to abandon their homes and flee."
