UK, Norway and US Foil Russian Arctic Cable Sabotage Exercise
Britain, Norway and the United States watched Russian submarines near Svalbard in the Arctic.
Western officials said the submarines were practicing how to damage important underwater cables.
These cables help carry internet traffic and satellite information.
The Russian vessels did not cut or damage any cables during the exercise.
The allied countries tracked the vessels and confronted them.
The vessels then left the area without finishing the exercise.
Russia’s Defence Ministry did not comment on the specific incident.
The Kremlin generally denies carrying out sabotage against NATO countries.
The countries involved said they wanted to show that suspicious activity near critical infrastructure would be detected.
British, Norwegian and U.S. forces tracked Russian deep-sea vessels near Svalbard during a spring exercise.
The vessels were linked by Western officials to Russia’s Main Directorate of Deep-Sea Research, or GUGI.
Officials said the exercise simulated deploying technology intended to disable undersea cables without leaving fingerprints.
The Russian vessels were confronted, prevented from completing the exercise and eventually left the area; no cables were damaged.
The operation focused on two fiber-optic cables connecting Svalbard with mainland Norway, which carry satellite data and support global communications.
