According to the expert, this news was not expected in Russia.

The news about the “attack of the Armed Forces of Ukraine” on the headquarters of the Black Sea Fleet of the Russian Federation seriously affected the Russians. They once again became convinced of the weakness of the “second army of the world.”
This was stated by the former speechwriter of Russian President Vladimir Putin, Russian political scientist Abbas Gallyamov on the air of Channel 24.
“The news that no one expected was the shelling of the headquarters of the Black Sea Fleet in Sevastopol. This is a completely different matter. This changes the perception of the war in the eyes of the Russians. A provocation is not a provocation, but the hostilities are actually transferred to the territory of Russia. For the Russians, this is a shock,” – he said.
At the same time, Gallyamov clarified that they say so, because the Russians consider the annexed Crimea to be theirs.
“We got to the headquarters with pinpoint precision. This is quite obvious clear evidence that the Russian army is not coping with its tasks. That is, they were going to take Kyiv in three days, and five months have passed and they are hitting Sevastopol – that’s how the Russians perceive it. And this delegitimizes Putin. If such things continue, it may happen before 2024 (Putin’s departure from power – UNIAN),” the political scientist added.
“Attack of the Armed Forces of Ukraine” on the headquarters of the Russian Black Sea Fleet
Earlier, Russia announced an “attack by the armed forces of Ukraine” on the headquarters of the Black Sea Fleet, located in the occupied Sevastopol. Five people were injured in the impact.

It seems to me that if Ukraine used a long-distance missile in Sevastopol there would have been a huge crater, not some little one like in the picture. It also looks like the Moscow monkeys are trying to use propaganda to cancel their Navy parade and now that propaganda has backfired because it looks like Sevastopol is vulnerable. Perhaps the Ukrainian Navy can show the monkeys in Sevastopol what a REAL Ukrainian missile strike looks like when it hits the Black Sea fleet…
I think it’s another Russian false flag, and this is an own goal. They’ve made themselves look vulnerable.
