For the Russian Olympics in Sochi officials have called up 37,000 police and security officers to help get a grip on the security in the Olympic city, but that has not completely help calm fears about security. Just one day after the U.S. started to warn the world about how explosives could be hidden in toothpaste or tubes of cosmetics, the Russian government decided Thursday to ban all gels, aerosols, liquids and powders on carry-on luggage for flights between the two countries.

The U.S. authorities are also working with Russian officials and those of other countries to try and shake up many possible threats such as this toothpaste issues. There have been various threats that vary in their credibility; the large threats can be found made by a group known as Imarat Kavkaz in Russia. This group has publicly said its members will try and cause a scene in the Olympic Games.

The U.S. ski and snowboarding teams have hired private security (Global Rescue) to help and provide additional protection to the individuals on the teams. So far it is not clear how much Global Rescue would be able to do on the chance there was a large scale incident as in times like these the Russian forces would be in complete charge. But the group has been gathering extra intelligence at the games about any possible threats and will help to provide an extra added layer of protection to the athletes.

So far, the targets of the threats have not just been the Americans. Austria claims two of its female athletes have received specific threats.

This is not just the first time such scares have been part of the lead up to the Olympics. Britain in 2012 had put missile launchers on roof tops and a large warship along the River Thames. In 2002, there was heightened security due to the events taking place right after the terrorist attacks of Sept. 11, 2001. Even before that, during the 1996 Olympics in Atlanta, the USA were subjected to a terrorist attack.
