British police are investigating whether Iran was behind a terrorist operation that was planned near the Fairford Air Force Base in the United Kingdom, where many American forces are stationed. This was reported by British media outlets Sky News and The Telegraph. Iran has previously threatened that it would strike the base if American bombers continue to take off from it for attacks on its territory. Additionally, U.S. President Donald Trump said after the arrest of the five suspects that "they planned to cause great damage, we could have been under a significant terrorist attack."
