In January 2026, sabotage of Baltic Sea undersea cables disrupted Nordic-Baltic internet traffic, raising fears of Russian covert attacks amid geopolitical tensions involving US threats to Greenland.
During the Christmas and early January 2026 period, Nordic countries broadly experienced disruptions due to undersea internet cable damage in the Baltic Sea, suspected to be sabotage with possible Russian involvement. The Baltic connector cable, crucial for Finnish and Estonian communication, was cut, causing extensive outages. Similar incidents have increased recently, prompting concerns about Russia aiming to destabilize Baltic states. The article highlights how these attacks on critical infrastructure threaten European security and NATO's collective defense posture. Meanwhile, political distractions unfold as former U.S. President Donald Trump's announcement to buy Greenland diverts attention from these strategic risks. Experts argue the cable sabotage underscores the hybrid warfare challenges facing the Baltic region and the necessity for improved resilience and defense cooperation among EU and NATO members.
Confidence: High
The article explicitly describes sabotage of undersea internet cables in the Baltic Sea causing disruptions to Nordic-Baltic communications, suspected to be hostile Russian hybrid warfare targeting critical infrastructure, clearly indicating aggressor activity. There is no mention of allied defensive measures in the article, so is_defense_prep_event is false.
