Three Al-Jazeera TV journalists were arrested in Paris on Wednesday after flying a drone from a park on the edge of the city, a judicial source said.
"The first was piloting the drone, the second was filming and the third was watching," the source said. There is so far no suggestion the journalists are linked to a series of night-time drone sightings over the city this week.
Officials with Qatar-based Al-Jazeera did not immediately respond to a request for comment.
