Mystery deepens as unidentified drones reappear over Paris

Unidentified drones have been spotted in the skies above Paris for a second night as authorities seek to determine whether the aircraft pose a security threat. Police say at least five drones were seen at locations including the U.S. Embassy, the Eiffel Tower and major thoroughfares in central Paris, as well as several of the city gateways. A police source said the unmanned aircraft were reported by witnesses and security forces.

Is it a game? Scouting for future operations? The investigation will show us.

The sightings are the latest in a series of unexplained drone flights in the French capital and elsewhere across the country. Authorities were first alerted to mystery drone flights in October, when state-run power company EDF filed a complaint with police. The company had detected tiny unmanned planes buzzing around the skies above seven atomic plants. The sightings continued into November, and altogether some 20 flyovers took place near nuclear plants. In January, a pilotless aircraft also flew over the presidential palace in Paris.
