Just this past weekend, the ISIS Army Caliphate made EVERY Christian in Mosul (ancient Nineveh) leave with nothing, not even their wallets, purses or cell phones, just the clothes on their back; or pay a $450 monthly Jerez tax, which is way more the poor Iraqi Christians earn in a quarter; convert to Islam (Wahhabi Sunni version ONLY) OR be beheaded.
God help any Jews they find.
