Terrorists could be planning to attack airplanes using passengers who have bombs implanted in their bodies, a U.S. security official said Wednesday.
The Department of Homeland Security (DHS) has discovered new information that the technique, which had been considered a possibility in the past, could be reemerging among terrorist groups. Security officials stress there is nothing to indicate any immediate threats, but DHS and the Transportation Security Administration have warned airlines and foreign nations to be on the lookout.
TSA spokesman Nicholas Kimball confirmed the agency was taking the threat seriously.
"Due to the significant advances in global aviation security in recent years, terrorist groups have repeatedly and publicly indicated interest in pursuing ways to further conceal explosives," he said in a statement. "As a precaution, passengers flying from international locations to U.S. destinations may notice additional security measures in place.
"These measures are designed to be unpredictable, so passengers should not expect to see the same activity at every international airport," he continued. "Measures may include interaction with passengers, in addition to the use of other screening methods such as pat-downs and the use of enhanced tools and technologies.
"We will continue to monitor information pertaining to threats against the United States and its interests, and as always, encourage the public and our partners in law enforcement and the private sector to remain vigilant in promptly reporting any suspicious activities,” Kimball concluded.
