EXCLUSIVE — There is credible evidence to suggest that British Special Forces were deployed to an air base used by the U.S. Air Force in the United Kingdom on Saturday.

Royal Air Force Lakenheath is technically a British Royal Air Force base but is utilized by the U.S. Air Force. The base has experienced more than a week of unauthorized drone incursions. More limited incursions have been reported at two other U.S.-utilized bases: RAF Mildenhall and RAF Feltwell. The U.K. military subsequently deployed counter-drone specialists to Lakenheath alongside launching search operations by other assets including Apache gunships.
