FBI chief James Comey revealed that at least 200 American citizens have either travelled, or attempted to travel to Syria in order to join the ranks of the Islamic State of Iraq and Syria (ISIS).
Comey, who was speaking to the Senate Select Committee on Intelligence on Wednesday, said the Bureau is taking the issue of radicalization of Americans as a ‘top priority’ amid raising concerns of a potential domestic attempts to attack US targets from within.
The FBI has arrested scores of Americans who were either recruiters or recruited to join the terror group.
The United States is leading an international coalition to launch airstrikes against ISIS positions in both Syria and Iraq.
Comey told lawmakers that ISIS is using ‘encrypted programs’ to deny law enforcement authorities from accessing their communications, making great benefits from social media networks to reach as many recruits as possible.
