The U.S. Air Force (USAF) in the UK says a small number of drones were spotted flying over bases in eastern England on Tuesday, including one base due to host US nuclear warheads. Tuesday's incident follows recent drone sightings in Suffolk and Norfolk,

The drones were detected between Wednesday and Sunday, near Royal Air Force Lakenheath, Royal Air Force Mildenhall and Royal Air Force Feltwell, all three of which are in eastern England. The bases house thousands of U.S. service members, primarily Air Force personnel.
