"With the" crawling "of the alliance into Ukrainian territory, the threats to Russia's security are sharply increasing," Antonov's words are quoted on the Facebook page of the Russian diplomatic service.
He stressed that "this is due to the prospect of the appearance in Ukraine of missile systems with a minimum flight time to Russia and other destabilizing weapons."
Earlier, Russian President Vladimir Putin said that Russia was "pinned" to such a line that "there is nowhere to move on."
Deputy Chairman of the State Duma Committee on International Affairs Alexei Chepa, in an interview with RT, commented on Putin's words.
In his opinion, if NATO continues to move towards the borders of Russia, it will be necessary to take protective measures, for which "we, as the president said, have all the technical means."
