Bombers Leave a British Base as Police Arrest a Suspect in a Possible Plot

British police arrested a 22-year-old on suspicion of terrorism offences connected to a possible plot against the RAF Fairford air base, according to PBS NewsHour. Over the weekend, the U.S. Air Force evacuated bombers from the base out of fear of an attack.

The two developments point in the same direction — a threat assessment serious enough to move aircraft, and a criminal investigation that has produced an arrest — even as the reported allegation remains at the level of a possible plot.
