Stockholm, Sweden – Swedish authorities have seized a vessel suspected of damaging an undersea data cable running through the Baltic Sea to Latvia, amid growing concerns over sabotage targeting critical infrastructure in the region.
The Swedish Prosecution Authority confirmed on Sunday that an investigation has been launched, involving the country’s police, military, and coast guard. Initial findings suggest deliberate interference, with prosecutors describing the incident as a possible act of sabotage.
The suspected attack follows a series of disruptions to key communication and power lines in the Baltic region, heightening security fears. Earlier on Sunday, Latvia’s military reported that two vessels were detected in the vicinity of the damaged cable. Authorities are now working to determine whether these ships played a role in the incident.
Nato’s Response and Rising Concerns
The latest cable damage comes less than a month after Nato launched its “Baltic Sentry” mission, aimed at increasing surveillance and protection of underwater infrastructure in the Baltic Sea.
The alliance has been on high alert following multiple attacks on undersea power and telecom cables in 2024, with some cases raising suspicions of Russian involvement.
Nato Secretary-General Mark Rutte emphasized the urgency of safeguarding critical infrastructure, stating that the alliance would respond robustly to future sabotage attempts. The Baltic Sentry mission is set to enhance monitoring efforts with additional patrol aircraft, warships, and drones.
Rutte also highlighted concerns over Russia’s so-called “shadow fleet”—ships with unclear ownership suspected of transporting embargoed oil and possibly involved in covert operations.
Although Moscow has not been directly implicated in this specific incident, previous infrastructure disruptions in the region have been linked to Russian activities. In late 2023, Finnish police opened an inquiry into potential Russian involvement in the sabotage of an electricity cable between Finland and Estonia.
Latvia, Sweden, and Nato Coordinating Efforts
Latvian Prime Minister Evika Siliņa assured the public that her country was closely coordinating with Sweden and Nato to address the situation.
The affected data cable is operated by Latvia’s state broadcaster, LVRTC, which reported “disruptions in data transmission services.” However, the company emphasized that end users would largely remain unaffected.
The attack underscores the vulnerability of the Baltic region’s undersea infrastructure, which plays a vital role in both civilian and military communications. In response, Nato allies are considering increased naval patrols and stricter monitoring of vessels operating in the area.
As the investigation into the damaged cable unfolds, Swedish authorities have not yet disclosed the identity or nationality of the seized ship. However, officials have indicated that further developments will be made public as the inquiry progresses.
With heightened geopolitical tensions and repeated infrastructure sabotage in the Baltic region, European nations and Nato remain on high alert. The incident further reinforces the need for enhanced security measures to protect vital undersea networks from potential adversaries.
