NATO plans to increase its military presence in the Baltic Sea following accusations of Russian sabotage on undersea power cables. Estonia has deployed a patrol ship to protect its Estlink1 cable after the Eagle S ship was linked to damage on the Estlink 2 cable. The EU has labeled the Eagle S as part of Russia's shadow fleet, with Estonia's Defence Minister emphasizing the need for protection of critical infrastructure. Finland and Estonia, both NATO members, are considering invoking Article 4 of the NATO Treaty for consultation on threats. Recent incidents have raised concerns about security in the region, with the EU working on sanctions against Russia's shadow fleet.
