Russian spy sensors have been discovered monitoring the UK’s nuclear submarines, raising serious national security issues. The operation is believed to be part of Russian President Vladimir Putin’s ‘greyzone’ warfare strategy. In response to this alarming development, the UK government is ramping up its defenses, collaborating on a new initiative with technology and energy companies. Additionally, authorities are contemplating implementing more assertive measures such as deploying sea mines around critical areas to safeguard against further espionage activities.
