Radio Liberty reports Andrei Soldatov, the editor of agentura.ru, a Russian site dedicated to terrorism and intelligence, says the Volgograd attacks -- which took place 650 kilometers northeast of Sochi, location of the upcoming Olympic Winter Games -- throw Russian security planning into disarray.
"I think the goal was to distract security forces. Because now, with the Olympics coming up, they'll be forced to think about ensuring the safety of the major Russian cities as well as Sochi and the infrastructure around the Olympic facilities," Soldatov said, says Radio Liberty.
"On top of that, they'll also have to pay special attention to Volgograd," says Soldatov. "It's an effective tactic -- diverting attention away from a place where the terrorists may be planning their next attack."
