Syrians using smugglers to seek refuge in Iraq

Refugees also fear that ISIL fighters may slip into Iraq, as security sources say 3,500 ISIL fighters have Iraqi citizenship.

The Turkish operation in northeastern Syria has forced more than a thousand Syrian refugees to cross the border into Iraq in the past three days.

But tightly secured borders mean many are being smuggled in to the country.

There are also security concerns about ISIL fighters slipping through.
