London: Despite spending over 30 billion pounds on the Winter Olympics, much of it on security, fears of a terrorist attack remain high in southern Russia following the two suicide bombings in the city of Volgograd in December, which killed 34 and injured over 100 people.

According to the Daily Star, a Pentagon spokesman said that air and naval assets, including two Navy ships in the Black Sea, will be available if requested for all manner of contingencies in support of - and in consolation with - the Russian government.
