Some Iraqi displaced citizens, who are set to return to the country from Syria's al-Hol Camp, were found to be families of ISIS fighters, said Kefah Mahmoud, an expert in the Kurdish affairs, on Friday.
Some of people could be dormant cells and hide among the displaced, Mahmoud said, adding that eye witnesses, especially from Yazidis, must look at the displaced people to pick out the ISIS members who have abused them, particularly in Baghuz.
The Iraqi government and the Syrian Kurdish authorities responsible for the camps agreed earlier to bring back the Iraqi refugees from those camps to the country.
