A fresh security scare has shaken US military operations in Britain after American aircraft were moved from RAF Mildenhall amid reports of a possible Iran-linked threat. At least 10 refuelling tankers and three Osprey aircraft were relocated to other bases across Europe. But another alarming development has emerged: British authorities have arrested a 41-year-old senior US Army soldier on suspicion of espionage linked to Russia. The suspect reportedly had access to sensitive information at a NATO military headquarters. Police say the two investigations are unrelated. Are Western military bases facing threats from multiple fronts?
