On November 11, 2026, the Finnish military detected an unusual strike on a Russian navy vessel in the Gulf of Finland while United States envoys held diplomatic talks abroad.
“detected … a strike on a Russian warship in the Gulf of Finland area and has monitored the development of the situation,” a spokesperson for the Finnish military said in an email to Reuters, adding that Finland is not under any immediate military threat, Al Jazeera reported.
The Finnish Defence Forces did not provide further details on the timing, exact location, or method of detection. Reuters reported that it remained unclear whether there were casualties or what caused the Wednesday strike.
Local media in Estonia, which shares a narrow arm of the Baltic Sea with Finland, reported that the targeted vessel was a small Russian navy ship returning to Saint Petersburg following the incident. Janes Defence Intelligence identified the vessel as the Project 21631 Buyan-M-class small missile corvette Naro-Fominsk, which was commissioned on December 23, 2023, and assigned to Russia’s Baltic Fleet.
Ukraine’s Security Service said that it planned and carried out the attack on the corvette, according to Finnish broadcaster Yle. The SBU connected the operation to a broader assault on port, oil-processing, and transport infrastructure near Ust-Luga close to Saint Petersburg on the night of November 11. The Armed Forces of Ukraine reported that five oil-product tanks, possessing a combined capacity of 150,000 square meters, sustained damage in a large fire.
The incident coincided with heightened regional friction across the Baltic Sea.
Amid these developments, US envoys Steve Witkoff and Jared Kushner met with Russian President Vladimir Putin in Moscow on Thursday before traveling to Ireland to meet Ukrainian President Volodymyr Zelenskyy. The shuttle diplomacy followed trilateral negotiations in the United Arab Emirates that yielded no major breakthroughs aside from an agreement on a large prisoner exchange.

“We are also working toward what would be the largest prisoner exchange of the war, potentially reuniting thousands of people with their families,” said Jared Kushner, US envoy, on X following the meetings.
Russian state-run news agency TASS reported that the anticipated prisoner exchange should take place within two to three weeks.
