Suspected drones drew a US Air Force security response.

The base is America’s main fighter base in England, already on raised alert.

KC-135 tankers began leaving RAF Mildenhall Monday as bases reportedly moved to Force Protection Condition Charlie over a threat from Iran.

The Air Force said no personnel, aircraft or infrastructure were affected.

Air Force officials declined to say who flew the drones or whether alert levels rose.
