Toothpaste and skin care products in the luggage of everyone heading to Sochi, Russia for the Olympics will be heavily scrutinized.
The United States has warned airlines that terrorists looking to disrupt the Olympic Games could conceal bomb-making components in toothpaste tubes.
The worry is that teams of operatives could smuggle those tubes on board a plane along with other component parts and then assemble an improvised explosive device while the plane is in flight, U.S. officials said.
They said the potential threat is aimed at Russia and the Sochi Olympics, which kick off Friday.
A U.S. intelligence source told CBS News on Wednesday that Russia has banned all liquids from being brought on board flights in carry-on baggage. Anything containing liquid, no matter how small an amount, must be in checked luggage.
