"With our leading mainstream outlets having become so unreliable, many of us now draw our information from alternative sources, but unfortunately these are often just as bad if not worse. As a result wildly exaggerated or incorrect stories can easily propagate across the Internet, including outright hoaxes." - Ron Unz.

"As reported on March 12 by the Greek portal of political and military information Pronews, citing American sources, in the course of an operation to retaliate for a provocation in the Bryansk region, a Russian hypersonic missile 'Dagger' struck at a joint Ukrainian-NATO command and communications center."

DEPENDING on the source, the underground joint Ukrainian/NATO command bunker located in Lvov or Kiev.

"Russian hypersonic missiles « Dagger » destroyed a secret bunker with 200 NATO and AFU officers"

LOSS of life that combined Ukrainian and NATO personnel very severe.

3. "Did Russian Forces Strike a 'NATO Command Center' in Lviv, Ukraine?"

From https://www.snopes.com | the article by Alex Kasprak | Apr 3, 2023.

"A lazy piece of obvious propaganda has become incorporated into several false claims about the war in Ukraine."

Claim:

"In early March 2023, Russian forces used a Khinzal [Dagger] hypersonic missile to strike an underground NATO command center, killing up to 300 people including at least 40 high level foreign advisors."

"According to sources familiar with the political behind the scenes of Bandershtat, the blow fell on the bunker control and planning centers, as well as on air defense / radar. Insiders reported heavy losses among the officers, including American ones. It seems that the 'shadow General Staff' of the proxy-NATO got a lot."

Bandershtat some sort of Ukrainian nationalist and cultural organization?

"The Anatomy of an Internet Hoax"

I highly recommend reading the Ron Unz article.

During the Cold War Lvov was where the headquarters of the Carpathian Military district was located. It is not unreasonable therefore to imagine some sort of command post dug deep into the ground with reinforced concrete protection of extraordinary thickness and robustness.

As to any such facility being occupied by a combined contingent of Ukrainian and NATO serving officers in command and command staff role, I just cannot confirm or deny. Can ANYONE else?
