The US military has moved at least 12 aircraft from RAF Mildenhall in England following an Iranian security threat.
9 KC-135 stratotanker refueling aircraft were redeployed to bases in Germany, Spain and Scotland, while 3 CV-22 Ospreys moved to nearby RAF Lakenheath.
US officials have confirmed enhanced security measures at both Mildenhall and Lakenheath, raising their alert status to force protection status (FPCON) Charlie, the second highest level, indicating that a terrorist act is considered likely.
The moves follow the early withdrawal of US bombers from RFF Fairford amid Iran-related threats.
The exact nature and proximity of the latest threat remain undisclosed, while US European Command declined to discuss specific aircraft movements or security measures.
