CBRN event in United Kingdom on Fri 20th March 2026

Two people have been arrested, one of whom is understood to be Iranian, after they tried to enter the Faslane nuclear submarine base in Scotland in what may have been an attempt at espionage. A man, 34, and a woman, 31, were detained by Police Scotland after they had asked to enter one of Britain’s most sensitive military sites late on Thursday afternoon. The base is home to the UK’s Trident submarines and not open to the public. It is understood that the man was an Iranian national, while the woman’s nationality was not immediately known. The incident is not being considered by the Ministry of Defence to be particularly serious at this stage. The pair did not gain access to the base, and their request to enter immediately prompted concern. They were arrested after they remained nearby and were deemed to be acting suspiciously, according to the Sun.
