Authorities in the United Kingdom are investigating security breaches and alleged reconnaissance activities targeting U.S. military installations. 

In Cambridgeshire, two Latvian nationals were arrested under the National Security Act 2023 after a security breach at RAF Molesworth, a major intelligence hub housing the NATO Intelligence Fusion Centre. The incident involved an abandoned vehicle and a breach in the base perimeter. Counter-terrorism police are investigating the motivations behind the entry.

Separately, court proceedings have commenced regarding an alleged reconnaissance operation near RAF Fairford. Prosecutors allege that individuals conducted surveillance of the base perimeter and transmitted images to a third party. The investigation includes the suspected procurement of surveillance equipment and vehicles, with officials examining potential links to foreign intelligence services.
