With about 100,000 police, security agents and army troops flooding Sochi, Russia has pledged to ensure "the safest Olympics in history." But terror fears fueled by recent suicide bombings have left athletes, spectators and officials worldwide jittery about potential threats.
Security experts warn that Islamic militants in the Caucasus, who have threatened to derail the Winter Games that run from Feb. 7-23, could achieve their goal by choosing soft targets away from the Olympic sites or even outside Sochi. Some have raised the possibility that jihadists could have infiltrated Sochi long before security was tightened and have noted the vulnerability of the city's transport systems.
"The most daunting threat is suicide bombers," Grigory Shvedov, chief editor of the Caucasian Knot, an online news portal focusing on the Caucasus, told The Associated Press.
