Russia's Foreign Intelligence Service (SVR) is not commenting on the arrests of 10 alleged spies in the United States accused of working for Moscow, its official spokesman told the RIA Novosti news agency. 'We are not commenting on this information,' spokesman Sergei Ivanov told RIA Novosti. The United States said Monday it had cracked open a massive alleged spy ring, announcing the arrest of 10 'deep-cover' suspects after unravelling a mission secretly monitored by the FBI for more than a decade.
