Russia's President Vladimir Putin has vowed to "fiercely and consistently continue the fight against terrorists until their complete annihilation" following the twin suicide bomb attacks on the city of Volgograd.
British Olympic chiefs are monitoring the safety and security situation in Russia after a second suicide bomb hit the city of Volgograd, killing at least 14 people.
The suicide bombing on a bus came a day after 17 people died in another suicide attack at the central station in the city.
With the Winter Olympics in Sochi, about 400 miles from Volgograd, due to open on February 7, the British Olympic Association described the terror attacks as "a painful reminder of the threats that exist in our world today".
"As with every Olympic Games - winter and summer - it is the responsibility of security officials at the national level, working in close coordination with regional and local authorities and the Games Organising Committee, to ensure that the environment is as safe and secure as possible," it said.
