COPENHAGEN, Denmark — The Danish defense ministry said Saturday that “drones have been observed at several of Danish defense facilities” overnight Friday into Saturday. The renewed drone sightings come after there were several drone sightings in the Nordic country earlier this week, with some of them temporarily shutting down Danish airports.

The Danish defense ministry did not say where exactly the drones were seen, but several local media reported that one or more were seen near or above the military Karup Air Base.

Danish public broadcaster DR reported that there were drones in the air both inside and outside the fence of the air base at around 8 p.m., quoting Simon Skelkjær, the duty manager at the Central and West Jutland Police.

DR said that for a period of time the airspace was closed to civil air traffic, but that did not have much practical significance as there is currently no civil aviation in Karup.

The repeated unexplained drone activity, including over four Danish airports overnight Wednesday into Thursday and a similar incident at Copenhagen Airport, has raised concerns about security in northern Europe amid suspected growing Russian aggression.

The Copenhagen drones grounded flights in the Danish capital for hours on Monday night,

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

For the upcoming European Union summit next week, the Danish defense ministry confirmed on X that the country’s government had accepted an offer from Sweden to “lend Denmark a military anti-drone capability,” without giving further details.

In neighboring Germany, several drones were reported in the northern German state of Schleswig-Holstein, which borders Denmark, from Thursday into Friday night.

The state’s interior minister, Sabine Sütterlin-Waack, said that “the state police are currently significantly stepping up their drone defense measures, also in coordination with other northern German states,” German news agency dpa reported. She did not provide any further details, citing the ongoing investigations.

German Chancellor Friedrich Merz said that in regard to frequent attacks on infrastructure and data networks, “we are not at war, but we are no longer living in peace either.” He did not allude to a certain country as the actor behind those attacks.

“Drone flights, espionage, the Tiergarten murder, massive threats to individual public figures, not only in Germany but also in many other European countries. Acts of sabotage on a daily basis. Attempts to paralyze data centers. Cyberattacks,” he added during a speech at the Schwarz Ecosystem Summit in Berlin on Friday, dpa reported.

What became known as the “Tiergarten murder” in Germany refers to the case of Vadim Krasikov, who was convicted of the Aug. 23, 2019, killing of Zelimkhan “Tornike” Khangoshvili, a 40-year-old Georgian citizen who had fought Russian troops in Chechnya and later claimed asylum in Germany. Krasikov was returned to Russia as part of a massive prisoner swap between the U.S. and Russia in 2024.
