Investigation: Five arrested near RAF Fairford on suspicion of terrorism offenses
Reports by BC BassheadBritish counterterrorism police arrested five men near RAF Fairford, a U.S. airbase in western England, on suspicion of explosive and terrorism offenses after receiving a tip about three suspicious vans heading toward the base. U.S. President Donald Trump stated the suspects were looking to do "big damage" and had been under investigation. The article reports that the base has been used by U.S. bombers to strike Iranian missile sites in the Strait of Hormuz with British authorization, and that investigators are considering an Iranian-linked motive as most likely, though Russian sabotage and Islamist plots are also being examined.
