Yes, it was all over Western media and twitter how they all died heroically. In fact Russia claimed they were still alive and had been taken as prisoners and were laughed at as being 'Russian Propoganda'.
The amount of misinformation in the media and twitter is insane.
I would guess the proportion of disinformation is about level on both sides.
But the volume of it coming from pro-Russian sources is going to be much bigger because of their greater resources. And, of course, more cnuty because they're the clear and obvious aggressors.
Either way, we should take everything with a pinch of salt. Even if we want it to be true.
Unless it's a story coming a verified source, I'm going to assume it's an exaggeration of some kind. And even then, it's probably worth waiting a couple of days for corroboration.
