Five men arrested near a UK air base in early hours of Sunday are being held on suspicion of preparing a terrorist act that may involve three trucks. The arrests were made near RAF Fairford, an air base used by the US during its war against Iran. The London Metropolitan Police received a call at 12:45 a.m. regarding three suspicious vehicles traveling toward the base.

This comes at a time of heightened tensions over threats from hostile states, with Russia and Iran among those accused of committing crimes on British soil. The number of national security cases linked to hostile states, including Iran, increased by 50% in the six months to December 2025.
