The United Kingdom and Norway jointly led a significant military operation in the North Atlantic, lasting over a month, aimed at deterring Russian submarines suspected of engaging in "malign activity." British Defence Secretary John Healey stated that a frigate, aircraft, and hundreds of personnel were involved in monitoring a Russian attack submarine and two spy submarines operating near critical undersea infrastructure north of the UK. Healey emphasized that the operation successfully compelled the Russian vessels to depart, sending a clear message to Russia that any attempts to damage vital infrastructure would face severe consequences. This operation underscores the UK's commitment to monitoring Russian activities, even amidst global focus on conflicts in the Middle East, with Healey identifying Russia as the primary threat to the UK and its allies.
