The UK Defence Secretary John Healey revealed that British naval forces have successfully tracked and deterred Russian submarines attempting to survey essential undersea infrastructure in the North Atlantic. This operation, which lasted more than a month, involved a Royal Navy warship and P8 marine patrol aircraft. Healey stated that these submarines were monitored while global attention was focused on the Middle East due to the US-Israel conflict with Iran. He made it clear that any attempts by Russia to damage UK cables or pipelines would not be tolerated and would result in serious consequences. While no damage has been reported, Healey indicated that UK forces would work with allies to verify the integrity of the infrastructure. He also highlighted the UK's capability to respond to threats, reinforcing the need for increased defence spending to ensure national security.
