England: Alarms sounded at RAF Lakenheath, Mildhall and Feltwell; Bases are locked for about 4 hours.
Alarms were activated at the three Royal Air Force bases, which also host American forces, due to suspected explosive devices and unidentified aerial objects. A person at RAF Lakenheath said the base was locked down due to drone activity, and several sources reported unidentified drones flying over the base. DefenseGeek sources said the FPCON level has been raised at one or more of the bases. Reports indicate the bases remain closed, although British authorities have said the incident is over.
