The shutdown is designed to prevent Isis from plotting amid escalating combat in the country. The organisation has its sights set on Baghdad, having already claimed the second largest city in Iraq, reportedly looting $420 million of central bank money and seizing military equipment.
A Facebook spokesperson told the BBC the mass block was "a matter of concern".
