BAGHDAD (Reuters) - After Islamic State seized Falluja in January it persuaded a man making covers for cars to sell suicide vests instead, one of many changes in the Iraqi city as it adapts to life under the ultra-hardline Sunni militants.

Islamic State is notorious for beheading or executing anyone who stands in its way when seizing cities and towns in Iraq and Syria that form its self-proclaimed caliphate, often using suicide bombers to make advances.
