Finnish Police Detain Russian Crew After Suspected Sabotage of Baltic Undersea Cable

Legal Insurrection has been following critical communication cables in the Baltic Sea over the past 2 years,

At the end of 2024, Sweden requested assistance in investigating the Yi Peng 3, a Chinese-flagged bulk carrier suspected of involvement in the incident. The ship may have dragged its anchor over cables connecting Sweden to Lithuania and Finland to Germany.

Then, on Christmas Day 2024, the Estlink 2 undersea power cable connecting Finland and Estonia experienced an unexpected outage, significantly reducing cross-border power transmission capacity between the two countries.

In early 2025, Finnish police investigated whether a Russian ship was involved in that incident, and NATO increased naval patrols in the Baltic after a cable connecting Latvia and Sweden was damaged by an anchor from a boat that had left a Russian port.

Now, as 2026 begins, Finnish authorities have detained the crew of the cargo ship Fitburg, which includes multiple Russian sailors, on suspicion that the vessel’s anchor cut an undersea telecommunications cable between Finland and Estonia in the Gulf of Finland.

A cargo ship severed an undersea telecommunications cable in the Gulf of Finland on Wednesday in what the Finnish police said they suspected was an act of sabotage that led them to seize the vessel.

The ship, the Fitburg, was en route from St. Petersburg in Russia to the port of Haifa in Israel when it damaged a cable connecting the capitals of Helsinki in Finland and Tallinn in Estonia, the authorities said.

The vessel was sailing under the flag of the Caribbean island nation of St. Vincent and the Grenadines at the time of the episode, which officials said happened around 5 a.m. local time.

The cut did not disrupt service, according to Elisa, the Finnish telecommunications company that operates the cable.

Finland’s Border Guard authority indicated sabotage was the likely motivation behind this incident during its press conference in Helsinki.

“At the moment we suspect aggravated disruption of telecommunications and also aggravated sabotage and attempted aggravated sabotage,” Helsinki Chief of Police Jari Liukku told reporters.

Concern is growing in Europe at what officials see as an increase in hybrid threats from Russia since it launched its war in Ukraine, which Moscow denies.

Earlier this month, NATO’s top military commander said the alliance must be ready to respond to these type of threats to defend its territory.

Hybrid threats refer to both military and non-military tactics designed to undermine an adversary’s security. They can include cyberattacks, disinformation campaigns, sabotage of key infrastructure and use of drones or irregular armed groups.

Interestingly, returning to the Christmas 2024 incident between Estonia and Latvia referenced above, Finland’s attempt to prosecute the Eagle S’s crew collapsed in court.

A court in Finland ruled that prosecutors had not been able to prove that the crew intentionally damaged the cables. The fact that the ship had been stopped in international – rather than Finnish – waters, led to a dispute about jurisdiction.

The Baltic Sea is crossed by as many as two thousand ships a day and has become one of the most fraught flashpoints between Nato allies and Russia.

In an interview with The Telegraph earlier this year, a top German naval officer said it could be very difficult to prove that a rogue crew had dropped and dragged an anchor on purpose.

“If you don’t have a well-trained crew, it might drop the anchor because they’ve been told to wait three days, or because there is a lack of orders, or because there is bad weather, and not realise there is a cable underneath them,” said Stephan Haisch, a Rear-Admiral in the Bundeswehr, the German armed forces.

I wish the Europeans adjacent to Russia and the Baltic Sea tons of good luck in 2026. They are going to need it.
