Great Britain and the US were caught in espionage.
According to a source in the Russian special services, several British military diplomats and a US citizen conducted illegal surveillance over the Russian Aerospace Forces sites in Mozdok.
As it was reported, United Kingdom Defence and Air Attaché in Moscow Carl Scott and Assistant Naval Attache Ryan Coatalen-Hodgson visited the Mozdok region of North Ossetia without permission at the beginning of March. They carried out covert surveillance, photo and video recording. The spies did not refute their acts, and refused to demonstrate the material, referring to the diplomatic immunity. After the British subjects were found guilty of an administrative crime, they were offered to leave territory, which is close to foreigners.
"The tests of the missile with characteristics prohibited under the Treaty took place only 16 days after Washington completed the denunciation of the said Treaty. It is obvious that it was not improvisation," Putin said
