Unidentified drones were spotted over three US air force bases in Great Britain, the BBC reported BC, quoted by BTA, citing US Air Force information.
Drone incidents were reported between Wednesday and Friday over three bases in Suffolk and Norfolk counties.
The US Air Force, which uses the bases, said it was unclear at this stage whether the drones should be considered "hostile" because there were no injuries to base residents or infrastructure problems. They also declined to comment on whether any defense mechanisms were used, but said they “reserve the right to defend the bases”.
F-35A and F-15E fighter jets are stationed at the bases, they also serve to refuel American combat equipment, deal with logistics and provide housing for military personnel.
A spokesman for Britain's Ministry of Defense, which owns the bases, told the BBC that threats were being taken very seriously and strict measures were being maintained at the defense sites, which included anti-drone capabilities, but declined to comment on security procedures. .
