MYSTERY drones shut down another Danish airport overnight, authorities confirmed.

It comes just days after Copenhagen Airport – the busiest hub in the Nordic region – was plunged into chaos amid claims Moscow is behind a string of sabotage across Europe.

Drones were spotted flying over the Karup Air Base on Friday evening.

Cops were involved in “an operation” due to a rogue drone flying both inside and outside the air station area, Danish authorities told Jyllands-Posten.

The sightings forced authorities to shut the airspace for civilian flights.

Karup Air Station shares a runway with Central Denmark Airport.

It comes after a string of mysterious drone sightings across European nations.

Danish Prime Minister Mette Frederiksen said they were part of “hybrid attacks” that may be linked to Russia.

She said: “Over recent days, Denmark has been the victim of hybrid attacks.”

Drones were also spotted on Wednesday and early Thursday at airports in Aalborg, Esbjerg, Sonderborg and at the Skrydstrup air base before leaving on their own, police said.

Aalborg airport, located in northern Denmark, was initially shut down for several hours and closed again for about an hour from late Thursday into early Friday morning due to another suspected sighting.

“It was not possible to take down the drones, which flew over a very large area over a couple of hours,” North Jutland chief police inspector Jesper Bojgaard Madsen said about the initial Aalborg incident.

A sighting of a suspected drone briefly shuttered a Danish airport on Friday for the second time in a few hours.

It came after a sighting earlier this week, which prompted Copenhagen airport – the busiest hub in the Nordic region – to shut down.

That followed a similar incident in Norway, drone incursions in Polish and Romanian territory and the violation of Estonian airspace by Russian fighter jets.

Investigators said they had so far failed to identify those responsible, but Frederiksen stressed: “There is one main country that poses a threat to Europe’s security, and it is Russia.”

Ukrainian President Zelensky claimed Moscow was behind it, referencing “Russia’s violation” of Nato airspace in Copenhagen in a social media post.

Though he did not provide any evidence.

Frederiksen said Thursday that she had spoken with nato chief Mark Rutte about the incidents.
