Concerns are growing that the Islamic militants fighting to take over Iraq are developing new types of undetectable bombs to specifically target the United States, and experts say the terrorists now pose an "extremely high" threat to the West.
"Several counterterrorism officials tell NBC News the threat from ISIS to American interests is, quote, 'extremely high.' They say ISIS is developing advanced bombmaking skills and cultivating a roster of foreign suicide bombers who could target the U.S. and Europe — and they're bragging about it," said
NBC News correspondent Richard Engel.
CNN reported that al-Qaida terrorists in Yemen have developed bombs with no metal and undetectable explosives. The weapons have the potential to circumvent airport screening systems posing "credible" security threats.
The top U.S. military commander in Europe told CNN that terrorists have been eyeing Western airports for months.
"We remain concerned about the capability of some of these elements to develop weapons that could be thwarted by our current security systems," Gen. Philip Breedlove told CNN.
"Detecting foreign fighters on the move is now a top priority for the intelligence community."
