Estonia confirms onboard blast but says the cause remains unclear Ukraine claimed on Wednesday that its drones had struck a Russian warship in the Gulf of Finland, as Kyiv continued to target Russian energy infrastructure. According to Ukrainian media reports citing the Security Service of Ukraine (SBU), a Buyan-M-class missile corvette belonging to Russia's Baltic Fleet was hit during an operation targeting oil infrastructure at the port of Ust-Luga, near the Estonian border. Estonian Defense Minister Martin Herem confirmed an explosion aboard the Russian Baltic Fleet vessel, adding that the ship subsequently headed towards St. Petersburg, Russia's second-largest city. “However, we cannot confirm whether Ukrainians are behind the attack or whether it was an accident,” Herem said. Finnish public broadcaster Yle, citing a senior Finnish official, also reported that Finland had detected an attack near the island of Gogland in the eastern Gulf of Finland. Ukraine previously claimed to have struck a Buyan-M-class vessel in the Sea of Azov in August 2025. Buyan-M-class corvettes can carry Russian-made Kalibr land-attack cruise missiles.
