According to Sky News, counter-terrorism police were investigating whether Iran is linked to the alleged bomb plot. Former Trump White House official Morgan Murphy told Fox News Digital that British authorities are leading the investigation along with U.S. authorities and intelligence services. “But since American airmen and bombers appear to have been targeted, Air Force investigators at the base, the FBI in London and American intelligence will likely work on the case.” “If conclusive evidence shows that Iran is behind an attempted attack on US forces, the US president will ultimately decide how Tehran pays,” Murphy added.

It could have damaged the nearby area.” US bomber base in the UK on Sunday.

The UK government had previously authorized US forces to use Royal Air Force bases Fairford and Diego Garcia. for limited defensive operations, including the destruction of Iranian missiles and launchers at their source. Iran’s Islamic Revolutionary Guard Corps (IRGC) later warned that any base used to attack Iranian territory would be considered a legitimate target. “Any base used to launch attacks on Iranian territory is a legitimate target for our forces,” the IRGC reportedly said. “Tehran warned London in July to keep US bombers away from Fairford, and if this plot is traced back to Iran, the response must be more bombers, not fewer,” Morgan said.

At that time, there was heightened surveillance around the area,” he told the outlet. Badger, however, cautioned against assuming that Iran was responsible and pointed to other potential threats. There are other actors too,” Badger added. “But there is Russia, which has been launching a gray zone campaign or hybrid warfare attacks across Europe, as well as Islamic extremists, who are still a significant threat here in the UK.” “Was this some kind of retaliation by Iran to perhaps try to gain influence or try to inflict a cost on the US withdrawing from these negotiations? Again, we don’t know for sure, but it’s a possibility,” Badger said. RAF Welford, a major US munitions storage facility that primarily supports operations at RAF Fairford.
