May 17 strikes by Ukraine’s SSU Special Operations Center “A” hit a Russian FSB headquarters near Henichesk on the Arabat Spit, destroying nine buildings and a Pantsir-S1 air-defense system.
Volodymyr Zelensky said the single operation left about 100 Russian troops killed or wounded, with drones striking roofs and flying through windows before triggering a large fire.
NASA’s FIRMS satellite service detected strong heat signatures at the site the same day, while local residents also reported a massive drone attack and blaze.
The Arabat Spit area has repeatedly hosted Russian troops and command centers, including a command post of the Dnepr group that Ukraine struck with Storm Shadow missiles in November 2023.
Zelensky cast the raid as part of sustained medium- and long-range attacks meant to make Russia feel pressure to end the war.
