A BBC News article reports that Finnish officials have confirmed a Ukrainian attack on the Russian warship Naro-Fominsk in the Gulf of Finland, with Ukraine's SBU saying it hit the ship in a drone operation that also struck tanks at Russia's Ust-Luga oil terminal. The BBC calls it the first such strike in open Baltic waters, while Estonia's defence minister says smoke rose from the ship, which headed back to St Petersburg, and Finland's foreign minister insists marine traffic faces no threat.
