Russian state-controlled media has been saying very little about the massive attack, but satellite images of the aftermath tell a story of sheer devastation.

A Ukrainian kamikaze drone strike hitting a major ammunition storage facility in central Russia on Wednesday was likely the most damaging long-range attack launched by Kyiv in 30 months of combat, and possibly the most devastating air strike ever to hit Russia, World War II included.
Kremlin-controlled information platforms on Thursday were downplaying damage reports and assuring the public that the situation was well under control. But one day after a Ukrainian nighttime air raid against Toropets Northeast Ammunition Depot, in Russia’s Tver region, evidence was pointing to a wildly successful long-range strike by Kyiv against a war-critical piece of Russian military infrastructure.
Following a 2018-2020 renovation of the site, Russian state-controlled media had billed Toropets as the most modern and attack-resistant munitions storage facility in all of the Russian Federation.
