Unidentified drones have been spotted over three British air bases used by the U.S. Air Force. U.S. Air Forces in Europe confirmed the sightings began last week, describing the drones as small unmanned aerial systems varying in size and configuration. Located in eastern England near Cambridge, the bases continue to monitor the situation alongside U.K. authorities. A Pentagon press secretary stated Tuesday that drones are being monitored but have caused no impact on operations or residents. The U.S. Air Force emphasized safeguarding personnel, facilities, and assets while declining to detail specific protective measures.
