NATO Secretary-General Mark Rutte on Friday said the alliance will increase patrols in the Baltic Sea region after Finland seized an oil tanker suspected of having damaged undersea power and internet cables this week.

NATO Secretary General Mark Rutte said on Dec. 27 that "NATO will enhance its military presence in the Baltic Sea" following the recent damage to the Estlink 2 power cable in the Gulf of Finland likely caused by Russia.

NATO Secretary-General Mark Rutte says the military alliance will step up patrols in the Baltic Sea area as Finnish investigators work to establish whether a ship linked to Russia sabotaged undersea cables there this week.

NATO said on Friday it would boost its presence in the Baltic Sea after the suspected sabotage this week of an undersea power cable and four internet cables, while alliance member Estonia launched a naval operation to guard a parallel electricity link.
