The mystery surrounding unidentified drones over French atomic plants has deepened with five more flights being recorded.
It comes after the government revealed on Thursday that seven nuclear plants across the country were flown over by drones between October 5-20.
Now, the state owned utility EDF says five other facilities have been flown over without any impact on safety or their functioning.
The drone sightings could trigger fresh concerns about the safety of nuclear plants in France, the world’s most nuclear-reliant country with 58 reactors.
Some security experts believe the environmental campaigning group Greenpeace is responsible as it has a history of breaking into atomic plants in France.
But the group has denied any involvement in the pilot-less flight activity.
