Finnish investigators have discovered a 100 km-long drag mark on the seabed linked to the Russian vessel Eagle S, suspected of causing damage to the Estlink 2 electricity cable.

The European Union is considering further sanctions against Russia's 'shadow fleet,' comprised of vessels operating to evade sanctions. This escalation underscores growing concerns about energy and digital infrastructure security amid the ongoing Ukraine conflict.
