(WASHINGTON) -- Travelers toting thermoses and insulated beverage containers through the nation's airports Friday might face heightened security measures, according to the Transportation Security Administration.
"The possible tactics terrorists might use include the concealment of explosives inside insulated beverage containers, so in the coming days, passengers flying within and to the U.S. may notice additional security measures related to insulated beverage containers," the TSA said in a statement released early Friday.
According to the TSA, while no specific threats have been reported, agents at airports have been trained to "detect a variety of threats, including the concealment of explosives in common items.
"Passengers traveling with insulated beverage containers can expect to see additional screening of these items using procedures currently in place, including X-ray screening, physical inspection and the use of explosives trace detection technology," read the statement.
The latest warning from the TSA follows a stronger one from the White House, which called for extra vigilant this holiday season, warning of a possible -- though unspecified -- terror threat from al Qaeda. The caution echoed a weeks' worth of warnings from law enforcement authorities.
"We remain vigilant to attempts by al Qaeda and other terrorist organizations to carry out cowardly attacks against innocent men, women and children, and we are working very closely with other governments to share all threat information immediately and to coordinate closely our counterterrorism and security activities," John Brennan, the White House counterterrorism chief, said in a statement earlier this week.
Attorney General Eric Holder, the FBI and Department of Homeland Security also alerted the public to a possible attack, citing a year's worth of thwarted attempts, beginning with 2009's Christmas Day "underwear" plot. It was a year ago that a suspected al Qaeda operative tried to detonate explosives packed in his briefs, onboard a flight bound from Amsterdam to Detroit.
