US evacuates aircraft from UK airbase over Iran security threat

The US military has reportedly evacuated aircraft from a British airbase following a threat from Iran, according to reports citing the Wall Street Journal.

US Relocates Aircraft and Raises Security Alert Levels at British Bases

The United States military relocated aircraft from RAF Mildenhall in Suffolk on Monday. According to flight-tracking data cited in reports, nine Boeing KC-135 Stratotankers and three Ospreys left the base during the afternoon and evening. Most of the refuelling tankers were moved to airbases in Germany and Spain, one was tracked to RAF Prestwick, and the three Ospreys moved to RAF Lakenheath in Suffolk.

In response to the situation, the US raised the security posture at RAF Mildenhall and RAF Lakenheath to FPCON Charlie. A US official told the Wall Street Journal that this is the third-highest level in the Department of Defense's Force Protection Condition system and applies when intelligence points to a form of terrorist action that is likely. It was earlier reported that a US official confirmed "enhanced force protection measures" at both bases, according to The War Zone. Lakenheath also asked the public to report suspicious drone activity, though it is not clear whether this is connected to the Iran threat.

Officials Weigh the Nature of the Threat Amid Prior Incidents

Sources familiar with the matter told the Wall Street Journal that the nature of the threat is under discussion among US officials, and it is not yet clear whether the threat is imminent or more general. AOL reported that it is understood that, on the ground, there has been no specific threat against the RAF base and no arrests have been made, suggesting the threat seen by the US was more general.

The evacuation follows the withdrawal of all 12 B-1 bombers from RAF Fairford in England last month. The Wall Street Journal reported that the bombers' withdrawal was driven by concern about an Iran-backed plot to kill American pilots and target the aircraft with drones, though Iran denied involvement. Director of National Intelligence Jay Clayton said in October that Iran was in "advanced stages" of planning to target US personnel in the Middle East. Asked about that concern on Monday, Secretary of State Marco Rubio said, "We've addressed it by moving people away from the threat." Congressional leaders known as the "Gang of Eight" received a briefing on Iran's threats on Monday, a person familiar with the meeting said.

Government Responses and Broader Diplomatic Context

Cabinet minister Lucy Powell told Sky News that the security of military bases in the UK was constantly under review. She stated she could not comment on live operations, but that authorities "take firm and quick action where we need to." A UK Ministry of Defence spokesperson stated: "We do not routinely comment on the activity of other nations. Aircraft and other assets move regularly according to operational requirements." A US Air Force spokesperson declined to give details on the matter, noting in a statement that aircraft rotate between installations for a variety of reasons.

The developments occurred alongside comments from US President Donald Trump. He told reporters on Monday, "Iran, militarily, is effectively over." He added, "We're just keeping it the status quo," and stated that Iran has been "decapitated," though he is still looking to ensure its nuclear programme is defanged. These were some of Mr Trump's most definitive comments about moving away from his threat to resume strikes on Iran after the midterm election.
