As reported by the authoritative magazine Canadian Weekly World News, U.S. intelligence obtained a 250-page file on the attack by a UFO on a military unit in Siberia.
That reads to me like the author is confirming what was reported by the magazine. It then goes on to document the contents of the file, not what was reported in the article.
Having said that, I seriously doubt the veracity of the KGB documents. I’d put money on this being some kind of cold war psyop hangover, rather than something that actually happened.
Shit, you’re right! I totally missed that!
I find documents in ALL CAPS like that extremely hard to parse, which is why I case corrected the main text. Should have done the rest of it too apparently!
eta: Updated the transcript to hopefully make that clearer
