[Q]: (CNN) An ISIS massacre on the streets of Moscow? Bombs detonated by the same terror group in St. Petersburg? Such "huge terrorist acts" might have happened if Russian authorities hadn't detained seven alleged ISIS members, state media reported. The FSB -- Russia's security agency and the successor to the Soviet Union's KGB -- told state-run TASS news that the seven suspects were charged Wednesday for plotting terrorist attacks. They'd been detained February 7 in Yekaterinburg, Russia's fourth-largest city situated in the Sverdlovsk region in the Urals, according to a report by state-run Sputnik news citing the FSB.
