Putin vows to annihilate 'terrorists' after bombings
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.
The International Olympic Committee (IOC) said it is confident the Russian authorities can delivers a "safe and secure" Winter Olympics in Sochi after a second suicide attack on the city of Volgograd.
IOC president Thomas Bach said: "This is a despicable attack on innocent people and the entire Olympic movement joins me in utterly condemning this cowardly act. Our thoughts are with the loved ones of the victims.
"I have personally written to the president of the Russian Federation, Vladimir Putin, to express our condolences to the Russian people and our confidence in the Russian authorities to deliver safe and secure Games in Sochi.
"I am certain that everything will be done to ensure the security of the athletes and all the participants of the Olympic Games."
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.
The Russian city of Volgograd where at least 31 people have been killed after two suspected suicide bombing attacks is about 400 miles northeast of Sochi, where the Olympics are to be held in February.
At least 14 people were killed in an explosion on a trolleybus earlier today, a day after a blast killed at least 17 at the city's main railway station.
