Denmark reports new drone sightings at armed forces' locations. NATO boosts Baltic Sea vigilance

COPENHAGEN, Denmark — The Danish defense ministry said Sunday it had again observed drones at several of its armed forces’ locations overnight, a day after NATO announced it would enhance its vigilance in the Baltic Sea region.

The ministry said in a statement it had “several capacities deployed” after drone sightings from Saturday into Sunday night. It didn’t offer any further details about the specifics of the deployment, the number of drones or locations.

This is the latest unexplained drone activity after several sightings, including over five Danish airports last week, raising concerns about security in northern Europe amid suspected growing Russian aggression.

Following a NATO meeting in Riga, Latvia, on Saturday, Colonel Martin O’Donnell, the Supreme Headquarters Allied Powers Europe spokesperson, announced that “we will conduct even more enhanced vigilance with new multi-domain assets in the Baltic Sea region, which includes Denmark, under Baltic Sentry.”

He also said NATO leaders were in constant contact with Danish officials following the drone sightings.

As Denmark gears up for the upcoming European Union Summit in Copenhagen, the Danish transportation ministry said Sunday that “all civilian drone flying in Danish airspace will be prohibited” from Monday to Friday to “remove the risk that enemy drones can be confused with legal drones and vice versa.”

“We cannot accept that foreign drones create uncertainty and disturbances in society, as we have experienced recently. At the same time, Denmark will host EU leaders in the coming week, where we will have extra focus on security,” Danish transportation minister Thomas Danielsen said in a statement.

“A violation of the prohibition can result in a fine or imprisonment for up to two years,” according to the statement.

The prohibition does not apply to military drone flights, drones used by state aviation, including police and emergency drone operations, as well as municipal and regional emergency and health-related drone operations.

On Sunday afternoon, the Danish defense ministry announced that the German air defense frigate, FSG Hamburg, had arrived in Copenhagen.

“Here, the ship will contribute to strengthening Denmark’s surveillance of the airspace in connection with the upcoming EU summit in Copenhagen,” the ministry said in a statement. “The German frigate is part of NATO’s Baltic Sentry activity, which is intended to strengthen NATO’s presence along the alliance’s eastern flank.”

Separately, Germany said that following a request from Denmark, its armed forces would provide military support for the upcoming EU summit through “Counter-small Unmanned Aircraft Systems capabilities,” also known as C-sUAS, which are detection systems that use radar, optical and acoustics technologies.

Sweden had already announced earlier that it would “lend Denmark a military anti-drone capability” without giving further details.

Tensions have been running high in Denmark in recent days following reports of drone activity, and hundreds of possible sightings reported by concerned citizens that couldn’t officially be confirmed. Nonetheless, the public has been asked to report all suspicious activity to the police.

Danish Minister of Justice Peter Hummelgaard said on Sept. 25 the goal of the flyovers is to sow fear and division, adding that the country will seek additional ways to neutralize drones, including proposing legislation to allow infrastructure owners to shoot them down.

While it is not clear who is behind the drone activity, Denmark’s prime minister and NATO’s secretary-general said last week that Russian involvement couldn’t be ruled out.

The Russian embassy in Denmark last week rejected claims of Moscow’s involvement in the incidents.
