The U.S. Air Force moved aircraft from the British RAF Mildenhall base following a threat linked to Iran.

The United States Air Force evacuated several aircraft from RAF Mildenhall in the United Kingdom on Monday, following the emergence of a threat that U.S. officials suspect may be linked to Iran. Two tanker aircraft were redirected to Germany, while other aircraft were subsequently moved to Germany and other operational locations.

The security level at RAF Mildenhall and RAF Lakenheath was raised to FPCON Charlie, the second alert level in the U.S. Department of Defense system. It is applied when intelligence indicates the likelihood of a terrorist action. The exact nature of the threat has not been publicly established.

The decision comes several weeks after the withdrawal of U.S. bombers from RAF Fairford, following a security incident. In September, five people were arrested near the base, while two others were later detained over alleged links to Iranian intelligence services. The case remains largely unresolved.

RAF Fairford had been used to launch U.S. attacks on Iran. Tehran denied involvement in the incident, but Iran's Islamic Revolutionary Guard Corps warned that bases used against Iran could be considered legitimate targets. The British Ministry of Defence and the U.S. Air Force offered no further details.
