Homeland Security in the United States has sent warnings to airlines flying to Russia that terrorists may smuggle explosives via flight hidden in toothpaste tubes.
Right now, millions are flocking to Russia for the Winter Olympics that is going to kick off in Sochi, this Friday.
All airlines that have direct flights to Russia have been warned. Some of them are flying from United States too.
According to The Guardian of February 6, the airlines were warned of explosive devices that could be assembled in flight or on arrival at the Olympics. Meanwhile, the department specifically added that it was not aware of a threat to the US.
Russian forces are also agile this time of a possible militant attack at the Games. Certain politicians have also expressed their concerns about security at the Black Sea resort, but President Barack Obama backed Russia by saying that Sochi is safe.
In December, a suicide mission killed 34 people in the Russian city of Volgograd, 400 miles northeast of Sochi. The attacks were seen with much concern, especially since the Olympics were set to be held this year.
The homeland security department said that they regularly share information with domestic and international partners, including those associated with international events such as the Sochi Olympics.
Looking inwards, Delta Airlines is the only direct flight which goes from United States to Moscow. Russian airlines Aeroflot and Transaero also operate several nonstop flights from the U.S.
United Airlines, the official airline partner of the Sochi Olympic team on the other hand only have charter flights to Sochi.
