Undersea telecoms cable linking Lithuania and Latvia is damaged, prompting a criminal sabotage probe.
A vital undersea optical telecommunications cable that connects Šventoji in Lithuania with Liepāja on Latvia’s western coast was found damaged, triggering a formal criminal investigation by Latvian authorities. The break occurred just kilometers off Liepāja, a key Baltic port city, and was first detected by Lithuania’s National Crisis Management Centre (NKVC) late the night before, which then alerted Latvian law enforcement. Investigators from both countries have opened a probe into the circumstances because the location and nature of the break — along a cable that has been operational since 1995 and is operated by Swedish provider Arelion — make accidental failure unlikely given the lack of weather or seismic events at the time. Latvian police boarded a vessel docked in Liepāja to question the crew over potential connection to the incident, although no official attribution has been publicly announced. In the backdrop, NATO and Baltic governments have noted a series of subsea infrastructure disruptions since 2022, including fiber-optic, telecom and power cables in the region, raising concerns about deliberate actions aimed at undermining allied resilience. The dynamics reflect hybrid-warfare logic: by targeting undersea digital arteries that are usually out of everyday public view, the event forces states to mobilise technical diagnostics, cross-border law enforcement cooperation, and strategic maritime domain awareness without conventional military engagement. Critics and analysts alike have framed the incident within a broader pattern of sustained pressure in the Baltic Sea region—where physical infrastructure, cyber networks and military postures intertwine in low-visibility arenas below the threshold of open conflict.
