The tower that was attacked by the drone in "Moscow-City" houses three Russian ministries at once: the Ministry of Economic Development, the Ministry of Industry and Trade, and the Ministry of Communications.
How did drones get in that close to Moscow? It could be partisan activity or special ops cross border. Not sure what drones would have the range to hit Moscow from Ukraine.
I’ve got to wonder if someone important was working late in that corner office. It doesn’t seem like a little drone either, most likely proper military hardware rather than an off the shelf model based on other drone strikes I’ve seen.
