Well, not *that* Moscow, it’s at the bottom of the sea. And not quite *that* Moscow, but the city of Tver, a few miles to the north west. It’s *probably* not related to Ukrainian sabotage, but… who knows? It’d be a dandy target and a propaganda coup if this fire was started by some Ukrainian Doolitle raider.

Fire At Russian Defense Ministry’s Research Institute In Tver Kills Six People

Reportedly this facility develops missiles of kinds used in Ukraine, and space weapons. The claim is that the fire is due to old wiring, and looking at that ancient building, I can believe it. But that’s not a whole lot better of an explanation for losing a “space weapon” laboratory than enemy action, any more than “it just caught fire” was a better, more comforting explanation than “It caught a couple anti-ship missiles.” If their work was related to weapon systems currently being expended, perhaps they had ramped-up work hours and an increased demand on the power and other systems.
