Alert issued on beverage containers on planes

From FoxNews.com:

The Homeland Security Department has alerted air carriers to a potential terror tactic involving insulated beverage containers like thermoses.

The alert stressed that there is no intelligence about an active terror plot, but travelers may notice airport screeners taking a closer look at empty insulated containers.

The Transportation Security Administration 'is carefully monitoring information related to terrorist tactics' in coordination with other nations, TSA spokeswoman Sterling Payne said in a statement Thursday. '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.'
