U.S. Air Force bombers stationed in the U.K. have returned to their bases in the United States due to a suspected terror threat possibly linked to Iran. A U.S. official reported that approximately a dozen B-1 bombers were among the aircraft extracted from Royal Air Force Station Fairford in Gloucestershire.

The Pentagon emphasized that while the bombers have been relocated, they are prepared to conduct long-range strike missions from the United States. RAF Fairford acts as the only European forward operating location for heavy bombers from the U.S. and plays a crucial role in U.S. military operations, including missions targeting Iranian sites.

Last Sunday, U.K. officials discovered three suspicious vehicles containing fuel accelerants near RAF Fairford. Although no improvised explosive devices were found, petrol quantities were recovered, leading to an investigation of possible ties to Iranian state proxies. Authorities arrested a British-Iranian dual national on suspicion of preparations for terrorist acts.

Secretary of State Marco Rubio highlighted the involvement of foreign actors in the suspected plot. In a statement, former President Donald Trump commented on the possible connection to Iran, noting the ongoing conflict with the nation since February.

A total of six arrests were made, including five British nationals, all in their early 20s. However, all suspects were released on bail, and the investigation continues. Officials assured the public that the release of suspects was a carefully considered investigative decision.
