The 2014 Sochi Winter Olympics are still months away, but they have already helped thaw chilly relations between Russia and Great Britain.
The Federal Security Service of Russia has met with British intelligence to discuss safeguarding the Games, according to the RIA Novosti news agency.
Russia and Britain had been at odds since Russian spy Alexander Litvinenko was fatally poisoned with radioactive polonium-210 while drinking tea at a London hotel in 2006.
But with the Olympics approaching, Russia has been reaching out to security officials in dozens of countries around the world.
Earlier this week, John Sawers, the head of British foreign intelligence, told a British parliamentary hearing about the discussions.
Sochi is considered vulnerable because of its proximity to the North Caucasus, where Islamic militants have waged a violent insurgency.
