A year ago, authorities estimated there were 15,000 foreign fighters in Syria and Iraq, including 100 Americans.

Several dozen of the fighters have made their way back to the United States, the report said. Additionally, 5,000 of the 30,000 carry western passports that would allow them to enter the United States without visas, according to the report.
