FBI director assumes Khorasan plots not disrupted

Plots against the U.S. and Europe by the al-Qaada cell in Syria known as the Khorasan Group may still be in the works.

FBI director James Comey told reporters at headquarters he has no indication yet that a series of airstrikes against the militants this week disrupted its plans.

U.S. intelligence officials say the group has been trying to perfect a non-metallic bomb that can get past airport security and be used to blow up an airplane in flight.

Comey says the group is comprised of al-Qaeda veterans from Afghanistan and Pakistan along with some newcomers, and it remains at the top of the FBI's list of terrorism concerns.

Comey adds that he also worries about a homegrown attack inspired by the Islamic State of Iraq and Syria (ISIS) group.
