FILE -- In this April 17, 2016 file photo, a long-range S-300 missile system is displayed by Iran's army during a parade marking National Army Day, in Tehran, Iran. State media says the military has begun deploying a Russia-supplied S-300 air defense system around the underground Fordo nuclear facility. Video footage posted late Sunday, Aug. 28, 2016, on Iranian state TV’s website showed trucks arriving at the site and missile launchers being aimed skyward. Russia began delivering the S-300 system to Iran earlier this year after sanctions were lifted under a landmark nuclear agreement with world powers. (AP Photo/Ebrahim Noroozi, File) less
