British counter-terrorism authorities are investigating a break-in at RAF Molesworth, a Royal Air Force base in Cambridgeshire that has been used historically to store US nuclear weapons. Two Latvian men, aged 32 and 36 and residing in the United Kingdom, were arrested in connection with the incident, which occurred during the early hours of the day prior to the arrests.

RAF Molesworth holds strategic significance due to its Cold War-era role as a site for so-called "doomsday" weapons operated by the United States. The break-in has raised concerns about base security amid broader regional tensions and security threats.

Separately, earlier in the year, RAF Wyton, located near RAF Molesworth and home to the UK’s Defence Intelligence Agency, experienced a theft targeting copper materials. This incident further highlights ongoing challenges in protecting critical defense infrastructure across the country.

Air Chief Marshal Sir Rich Knighton emphasized the armed forces’ commitment to securing military installations in Europe, stating, “We take the security of all of our bases in Europe seriously.” His remarks came following questions about security measures after the withdrawal of US bombers from RAF Fairford in Gloucestershire, reportedly prompted by fears of an Iranian drone threat.

In total, seven individuals have been arrested in connection with a suspected plot involving the RAF Molesworth base, although details of the alleged plan have not been disclosed. Authorities continue to investigate the full circumstances surrounding the break-in and related activities at the site.
