An individual from Iran has been apprehended for trying to access the naval facility where the United Kingdom’s four nuclear submarines are stationed. The 34-year-old man, accompanied by a woman of undisclosed nationality, approached the entrance of HM Naval Base Clyde, commonly referred to as Faslane, on Thursday in a vehicle.

As reported by The Times, the pair was denied entry due to a lack of proper security clearances but later caught behaving suspiciously in the vicinity and subsequently detained. Police Scotland confirmed the incident, stating that they were alerted to the attempt by the two individuals to enter HM Naval Base Clyde on Thursday evening. The 34-year-old man and 31-year-old woman have been taken into custody in connection with the incident, with investigations ongoing.

No specific details have been disclosed regarding the nature of the suspicious behavior, such as whether they were trying to take photos or engage in other prohibited activities at the base. A spokesperson from the Royal Navy mentioned that Police Scotland had arrested two individuals who unsuccessfully attempted to access HM Naval Base Clyde on March 19. They refrained from providing further comments as the matter is under investigation.

Faslane serves as the operational base for four Trident-armed ballistic missile submarines, which constitute the UK’s continuous at-sea nuclear deterrence. Additionally, the base accommodates the Royal Navy’s seven Astute-class nuclear-powered attack submarines capable of launching precision Tomahawk land-attack cruise missiles targeting locations hundreds of miles inland.
