The damage caused to submarine cables in the Baltic Sea caused a significant amount of additional costs for Finland's Border Guard and law enforcement, according to the finance ministry's second supplemental funding proposal.
The ministry has set aside nearly 4.4 million euros for the Border Guard's efforts to protect critical subsea infrastructure and police investigations.
The ministry also allotted around 700,000 euros for police investigation costs related to damage caused to the Estlink 2 electricity cable between Finland and Estonia around Christmas.
Additionally, four subsea telecommunications cables were damaged on Boxing Day 2024.
Authorities suspect the Cook Islands-flagged Eagle S tanker ship's anchor was behind the damage to Estlink 2. The ship is thought to be part of Russia's "shadow fleet" of sanctions-breaking oil tankers.
Finnish authorities detained the Eagle S after the incident, but the vessel was released in early March.
Finland's National Bureau of Investigation (NBI) investigated the incidents as cases of aggravated vandalism and aggravated interference with telecommunications.
The government is expected to negotiate the supplemental funding plans on 27 May.
