Amid the push by Iraqi government forces to retake Mosul from Islamic State (IS), some former inhabitants of Christian villages in the Nineveh Plains and northern Syria are refusing to go back because they believe their former Sunni Muslim neighbours were complicit in driving them out, says Middle East analyst and former journalist, Patrick Cockburn, in News Deeply.

Christians returning to Nineveh believe Sunni Arab villagers were complicit in “taking their houses, killing and raping people,” he says.

Cockburn adds that, in Syrian towns occupied by IS, Christians believe their Sunni Arab neighbours were similarly cooperating with IS and that returning Christians might drive Sunnis out in turn. There’s a “real, very high level of friction and hostility on the ground, which I think is going to be extraordinarily difficult to reverse”, he says.

“A longer-term and very dangerous shift in both Iraq and Syria is that communities in general can’t live together any longer.”

In November Archimandrite Emanuel Youkhana, a priest in the Assyrian Church of the East and head of CAPNI (Christian Aid Program Northern Iraq), said that defeating IS won’t guarantee Christians’ return.

“What are the guarantees that it will not happen again?” he asked, noting that Iraqi Christians had been targeted not only since IS’s sudden appearance in 2014 but since the US-led invasion in 2003, after which he said the fabric of Iraq “was broken”.

In the decades before IS, more than a million Christians left Iraq, which had turned increasingly hostile towards them, the minority population felt.
