UK police are investigating a potential terrorism incident after arresting five men near a UK air base used by the United States. Multiple outlets report the arrests happen in the middle of the night, and the men are held on suspicion of preparing a terrorist act.

The reporting also says counter-terrorism officers are assessing what occurred at or near the air base, including suspected explosives. One outlet adds that the arrests involve possible offences under the Explosives Act. Another set of reports describes police examining alleged links to the Iranian regime, framing the case as connected to an alleged plot involving Iran.

Across sources, the core details remain consistent: five men are detained, police investigation is ongoing, and the location is an air base used by the US Air Force. Differences mainly concern emphasis—some focus on the terrorism suspicion, others on the explosives angle or on alleged Iranian links—while all indicate uncertainty and active police work to establish facts.
