Paris - Paris police on Wednesday said the public had reported around a dozen drone sightings over sensitive areas of the French capital - the latest in a baffling series of overflights.
Authorities are now scrambling to work out "if all the reports were really drone flights", said a police source who declined to be named.
No arrests were made over the flights, which reportedly took place overnight on Tuesday near the River Seine, the Place de la Concorde, the Invalides military museum and around the Paris ring road.
