Denmark's Aalborg airport, used for commercial and military flights, was closed due to drones in its airspace, police said early on Thursday, two days after the country's main Copenhagen airport was shut over drone sightings that raised European security concerns.

Danish national police said the drones followed a similar pattern to the ones that had halted flights at Copenhagen airport for four hours a few days earlier. Local police later said the drones had left the Aalborg area after about three hours.
