The Fairford arrests warrant a public explanation of the evidence for an alleged plot

British police arrested five men near RAF Fairford, a base used by the U.S. Air Force, on suspicion of explosives offences and preparing a terrorist act. Counterterrorism police are investigating, but no target, ideology or completed attack plan has been publicly established. British counter-terrorism police later arrested a 22-year-old man in Westminster on suspicion of preparing terrorist acts; six earlier suspects had been released on bail. Anonymous US officials described concerns about an Iran-linked drone plot, but British police have not publicly attributed the suspected plot to Iran; Iran denies involvement. Provisional: keep until charges are filed or the intended target and character of the alleged plot are established.
