The Interfax news agency today quoted Alexander Gordeyev, spokesman for the Far Eastern Military district, as saying that the movement of heavy weaponry, caught on film and widely distributed on social media, is part of "absolutely scheduled manoeuvres of combat readiness."
Gordeyev said the military hardware was on its way back from drills elsewhere and denied any connection to the tensions around North Korea's nuclear program.
In Moscow, first deputy chairman of the defence committee at the Federation Council Frants Klintsevich told RIA Novosti the movement was pre-planned and dismissed reports suggesting Russia was preparing for a possible US attack on North Korea as speculation.
