The International Olympic Committee president has said that he is confident Russian authorities will deliver a `safe and secure' Winter Olympics in Sochi in 2014 despite the two blasts that occurred in two days in the city of Volgograd.
Investigators say the attacks on a railway station and trolleybus, which killed at least 31 people, were linked, and they struck just over a month before the Winter Olympics begin.
According to the BBC, although to the threat to the Sochi Games may not be so big as there are adequate police officers and military personnel deployed around the area, it is however, widely assumed that the people who carried out the Volgograd bombings were mainly targeting the Games.
However, IOC President Thomas Bach said that he is certain that the Russian government would do everything in their power to ensure the security of the athletes and all the participants of the Games, which would open on February 7.
But the report said that despite intense security in Sochi, Russians are palpably nervous that following these attacks in Volgograd - which lies 700km north-east of Sochi - bombers could also strike elsewhere.
The US condemned the attacks and offered its 'full support' to the Russian government in security preparations for the Sochi Games, the report added.
