The United States was reported to be removing tanker aircraft from RAF Mildenhall near Cambridge because of a threat from Iran. Two aircraft were due to leave for bases in Germany, with others to follow later. It was unclear whether the move was prompted by a specific threat or by Iran’s broader warnings against US military bases involved in the war.

Earlier, the US had also moved bombers from RAF Fairford. British defence officials did not comment, citing a policy of not discussing other countries’ troop movements. Iran’s Revolutionary Guards had previously said that bases involved in the war would be considered legitimate targets.
