THE government was urged today to end its “wall of secrecy” over drone sightings at three air bases in East Anglia amid escalating tensions with Russia.

The US Air Force has confirmed “unmanned aerial devices” were spotted over RAF Lakenheath, which is set to house US nuclear weapons, RAF Mildenhall in Suffolk and RAF Feltwell in Norfolk between November 20 and 22.

Unconfirmed reports claim F-15E Strike Eagles were scrambled to chase the drones, which affected the flight operations at the bases.
