On October 29, the Russian-appointed so-called governor of occupied Sevastopol, Mikhail Razvozhaev, said that residents of the city heard explosions caused by a Ukrainian “drone attack.”
The media outlet Censor.net reported that at least three Kalibr cruise missile carriers of the Russian Navy were damaged in the blasts, citing a source from the Security Service of Ukraine. “Most likely several ships sank.”
Later, the Operational Command South, a formation of Ukrainian Ground Forces, suggested that unsuccessful launches of Russian anti-aircraft missiles could have caused the explosions in Sevastopol.
Ukraine hasn’t claimed responsibility for the alleged drone attacks.
Footage of the attack on Russian ships emerged allegedly filmed by cameras of Ukrainian surface kamikaze drones in Sevastopol, Ukrainian journalist Yurii Butusov has published it saying that it was a joint operation of the Armed Forces of Ukraine and the Security Service of Ukraine:
Ukrainian journalist Andrii Tsaplienko published four-minute footage of the alleged Ukrainian surface drone attack on Russian warships in Sevastopol.
He wrote that the footage confirms that “at least three Russian Kaliber missile carrier ships were damaged. Among them is the Admiral Makarov frigate. There is a good chance that several ships are not just damaged, but sunk.”
“None of the siloviki services officially confirmed that the Ukrainian special services might be behind the explosions. But coincidentally, a trolling photo captioned ‘It’s BAVOVNA o’clock!’ was published on the SBU” Twitter account:
The “bavovna” (‘cotton’) is a Ukrainian humorous term for explosions in Russia and the Russian-occupied territory based on mistranslated Russian term хлопок (“clap, pat”) used in Russian media to downplay the seriousness of explosions occurring in Russia, this word is spelled in the same way as хлопок (‘cotton’), which machine translation from Russian often turns into the Ukrainian бавовна ‘cotton’.
