Norway and Sweden have heightened security measures in response to a series of incidents involving damage to undersea cables in the Baltic Sea, with multiple Russian-crewed ships detained on suspicion of sabotage. At least 11 Baltic cables have been reported damaged in recent months, leading NATO to increase its vigilance and responses in the region. Investigations are ongoing, with Norway releasing one ship previously suspected of involvement, while another was seized amid police inquiries. The escalating situation has prompted discussions about greater protection for undersea infrastructure, with proposals including a dedicated shipping tax put forth by Estonia. As European nations grapple with these security challenges, the calls for action against potential threats to critical communication links intensify.
