FBI Director James Comey said he knows the identities of roughly a dozen Americans fighting alongside terrorists in Syria, Bloomberg reports.
Comey said the bureau is prepared to track the U.S. citizens if they return.
“Ultimately, an American citizen, unless their passport’s revoked, is entitled to come back,” Comey said in a taped interview for CBS’s “60 Minutes” program airing Monday.
“So, someone who’s fought with ISIL, with American passport, wants to come back, we will track them very carefully,” he said
Last month, Defense Secretary Church Hagel estimated there were more than a 100 citizens fighting with ISIL forces. The Pentagon responded that there may be 100 U.S. residents inside Syria, but only about a dozen are fighting with terrorists.
