Under-sea fibre-optic cable between Latvia and Sweden damaged, suspected sabotage.
On the morning of 26 January 2025 Latvian authorities detected a break in a key submarine fibre-optic communications cable landing at Ventspils, which also disrupted data-flows to Sweden via Gotland. Swedish prosecutors swiftly opened a sabotage investigation after evidence showed the break was likely caused by external influence rather than accidental damage. The Ventspils landing point places Latvia at the frontline of Baltic-Sea submarine infrastructure routes, and the break occurred in a zone accessible to Russian maritime assets and shadow-fleet vessels. By severing a communications link, an adversary forces Latvia to devote resources to investigation and restoration, raises uncertainty about national digital-resilience, and signals capability to strike infrastructure beneath the threshold of open war. The incident prompted Latvia to coordinate with Sweden, NATO allies and maritime-domain authorities to track vessels in the area, raise submarine-cable surveillance and upgrade resilience measures. While no public attribution pinned the break on the Russian Federation, security-analysts pointed to the pattern of prior Baltic-Sea infrastructure disruption linked to Russian “shadow fleet” activity. The case underscores how Latvia’s digital-communications backbone is embedded in maritime geography and vulnerable to hybrid threats that combine maritime presence, ambiguity of intent and critical-infrastructure targeting.
