US personnel are due to leave RAF Mildenhall within the next decade (Library picture: MOD).
RAF Mildenhall's main gate has reopened, following the discovery of a suspicious package.
A cordon had been put in place at the Suffolk base's main gate after the incident.
The gate reopened at 5:18pm after it was assessed that the package posed no risk to personnel or the public.
RAF Mildenhall's main role is to support United States Air Force personnel, and it is currently home to 100th Air Refueling Wing.
It was announced last November that hundreds of US personnel and their families would be relocating from the base in the coming years.
Mildenhall will stay open until at least 2027.
