to be clear, this was the property of the Russian government used as part of the defense industrial baseWoah. Drone attack on Moscow International Business Center.
Which makes this very confusing, as this could be:
1. false flag attack (remember, this is how Putin launched* the 2nd Chechnya war)
2. misdirected Ukrainian drone ( Russia likes to ew jam drones and redirect them at 90 or 180 degrees from their target )
3. the actual target of a Ukrainian drone
It is Russia, so we will never know.
