The US Homeland Security Department is banning all liquids from hand luggage for non-stop flights from the United States to Russia.
The ban comes after the department warned airlines that terrorists might try to smuggle explosives on board hidden in toothpaste tubes. The warning said terrorists might try to assemble explosive device in flight or upon arrival at the Olympics.
Delta Airlines, the only US airline with regularly scheduled non-stop flights to Russia, posted a warning about the Transportation Security Administration policy yesterday.
The government warning became public on the eve of the Winter Olympics in Sochi, Russia. Homeland Security has said the government is not aware of a threat to the US.
