Finland says it detected a strike on a Russian warship in the Gulf of Finland; Ukraine says it hit the missile ship Naro-Fominsk
Finland's Defence Forces said they detected a strike on a Russian warship in the Gulf of Finland on Wednesday, and Estonia's defence minister said an explosion occurred aboard a Russian Baltic Fleet vessel, which then headed towards St Petersburg. Ukraine's Security Service (SBU) said it carried out a drone strike on the Buyan-M missile ship Naro-Fominsk, near Gogland Island, as part of a wider operation against the Ust-Luga port area. Russia has not confirmed any strike on a warship, and neither Finland nor Estonia named the attacker — the SBU's claim, the damage and any casualties are not independently verified.

What happened
Russian and Ukrainian vessels have been targeted repeatedly in the Black Sea since 2022, but a strike in the Gulf of Finland — a narrow, busy waterway between Finland, Estonia and Russia's St Petersburg coast — would take Ukraine's naval campaign into the Baltic for the first time. That is why two NATO states on the Gulf are the sources settling what can be said: both detected an incident, and neither has attributed it.
What we know / what we don't know yet
What we know
- That Finland detected a strike on a Russian warship, and Estonia observed an explosion aboard a Baltic Fleet vessel that then headed for St Petersburg.
- That Ukraine's SBU claims the Naro-Fominsk strike, and that Russia has not confirmed any warship strike.
What we don't know yet
- Whether the ship Estonia observed was the Naro-Fominsk, and what caused the explosion.
- How badly any ship was damaged, and whether any crew were killed or injured — a claim of crew casualties from an unnamed source is unverified.
- Russia's account of the incident — none has been published in the reporting read.

Why this label: That a strike on a warship was detected is Finland's own statement, reported by Reuters and the BBC. Finland did not name the attacker or the ship.
On the ladder: a claim earns Verified from primary evidence, or from two independent sources that do not copy each other.
Why this label: Herem's account is the Estonian minister's own statement to ERR. He expressly did not settle the cause, and whether the ship he described is the Naro-Fominsk is not established.
On the ladder: a claim earns Verified from primary evidence, or from two independent sources that do not copy each other.
Why this label: This is the SBU's claim, carried as a claim. The SBU gave no evidence of damage in the reporting read, and no independent source has verified that this ship was hit, how badly, or whether any crew were hurt.
On the ladder: the evidence so far sits low — early, single or social sources. We publish the claim as a claim, never as fact.
Why this label: The absence of a Russian confirmation is part of the record: Moscow's silence neither confirms nor denies the SBU claim.

Why it matters
If Ukraine can reach a missile ship in the Gulf of Finland, Russia's Baltic Fleet is in range far from the Black Sea war — and every such incident happens minutes from Finnish and Estonian waters, where a misread explosion can pull NATO states into a crisis they did not choose.
Background
A wider Ukrainian drone operation targets the Ust-Luga port area; Finland restricts airspace and maritime areas in the eastern Gulf of Finland as a precaution.
Estonia reports an explosion aboard a Russian Baltic Fleet vessel, which then heads towards St Petersburg.
Finland confirms it detected a strike on a Russian warship; the SBU's claim on the Naro-Fominsk is reported.
