As UNIAN reported earlier, NATO accused Russia of escalating a disinformation campaign since the Kremlin's 2014 seizure of Ukraine's Crimea region, saying Russian websites such as Sputnik and RT had posted false stories.

"NATO has been dealing with a significant increase in Russian propaganda and disinformation since Russia's illegal annexation of Crimea in 2014," spokeswoman Oana Lungescu said in an email.

She said a website set up by NATO in 2014 "catalogs 32 Russian myths about NATO systematically used by Sputnik, RT and a range of other outlets owned or controlled by the Russian government."
