The Homeland Security Department is warning that terrorists could try to hide explosives in shoes. New intelligence suggests terror groups are working on plans for a new kind of shoe bomb, which prompted Homeland Security to warn airlines to be on the lookout for such devices on oversea flights to the U.S.
There is no known plot or specific threat, but passengers may undergo more searches.
Earlier this month the agency warned airlines with flights to Russia to be on the lookout for explosive devices possibly hidden inside toothpaste.
