Why is Ukraine attacking Russian warships in the Baltic Sea amid talks?

What the report says

Finland’s military said it detected a strike on a Russian warship in the Gulf of Finland, near its coast, while Ukraine and Russia were holding US-brokered talks in Abu Dhabi. The report came amid a broader Ukrainian drone attack on Russia’s northwestern Leningrad region, including the port area of Ust-Luga, which regional officials said was hit and where three workers were injured. Estonia, Latvia and Lithuania also warned residents to seek shelter after drones entered or neared their airspace, prompting a NATO response.

Al Jazeera reported that the incident appeared to be a rare Ukrainian attack on a Russian navy vessel in the Baltic Sea. Finnish officials said there was no immediate threat to Finland, but Helsinki later raised the issue with Kyiv because of concerns about civilian shipping and environmental safety in the narrow Gulf of Finland. The article said the ship was believed by Estonian media to be a small Russian navy vessel that later returned to St Petersburg, though casualties were not confirmed.

Ukrainian officials said their forces had targeted the Buyan-M-class missile ship Naro-Fominsk, while Kyiv also said drone strikes damaged fuel storage at Ust-Luga. The timing matters because the attacks came as diplomacy was continuing, with no major breakthrough from the Abu Dhabi meetings beyond a reported prisoner exchange agreement. Analysts quoted by Al Jazeera said Ukraine is trying to keep pressure on Moscow while showing it remains willing to negotiate from a position of strength.
