An exodus of Christians is under way in the southern district of Dora after groups affiliated to al-Qa'eda issued a threat of "convert or be killed".
Most have fled to Kurdish northern Iraq, where the village of Ankawa has grown into an overcrowded "city of Christ", while others leave for Syria or Jordan.
Priests claim that half Baghdad's pre-2003 Christian population - estimated in the hundreds of thousands - has fled or been killed. They also claim that the Iraqi government is failing to protect them.
And even the surge can't save them.
