That there was a surge in numbers of explosions in East Ukraine is not Russian propaganda, everyone agrees it happened.
That the surge in shelling was Ukraine-initiated against Russian-backed separatists (and not vice versa coordinated from Moscow as part of the prelude to its own invasion)—and, even moreso, that even if it was, a Ukrainian offensive against separatists in Ukraine (and not even against the openly Russian-occupied part) was a reasonable basis for seeing a threat of NATO invading (or backing an invasion of) Russia—is the Russian propaganda.
