Denmark has recently experienced a series of suspicious drone activities, particularly near its military facilities, prompting concerns about national security and potential foreign involvement. The latest incidents included drones observed overnight above Karup airbase, Denmark's largest military base, which houses all of the Danish Armed Forces' helicopters, airspace surveillance, and parts of the Danish Defence Command. This activity forced Karup airbase to briefly close its airspace to commercial traffic, although no flights were affected as none were scheduled at the time.

These drone incursions are part of a broader pattern. Earlier in the week, similar sightings caused air disruptions and airport closures across Denmark, including Copenhagen, Aalborg, and Billund airports, some of which also host military facilities. Oslo airport in Norway also experienced temporary shutdowns due to drone reports. Possible sightings have also been reported in Germany, Sweden, Norway, and Lithuania, indicating a wider regional issue.

Danish authorities have characterized these incursions as a "hybrid attack," a term used for a mix of military and non-military tactics designed to interfere with a nation's infrastructure or institutions. Denmark's defence minister stated the attacks appeared to be the work of a "professional actor" and likely launched locally. While initial statements cautioned against directly implicating Moscow, Danish Prime Minister Mette Frederiksen has pointed to Russia, stating, "There is one main country that poses a threat to Europe’s security, and it is Russia."

Russia, through its embassy in Copenhagen, has "firmly rejected" any suggestion of its involvement, labeling the accusations as "absurd speculations" and the incidents as "staged provocations." Kremlin spokesman Dmitry Peskov has also called the allegations "unfounded."

The current wave of drone activity comes shortly after Denmark announced plans to acquire long-range precision weapons for the first time, citing Russia as a threat for years to come, and to enhance its capabilities for detecting and neutralizing drones. The incidents have left Denmark feeling exposed and searching for an adequate response. The broader European context is also significant, with other NATO members reporting Russian incursions. Estonia and Poland requested consultations with NATO after Russian drones crossed into Poland and jets entered Estonian airspace. Romania, another NATO member, also reported a Russian drone breach.

In response to these growing concerns, defence ministers from ten EU countries agreed to prioritize a "drone wall" for the bloc, drawing lessons from Ukraine's experience. EU defence commissioner Andrius Kubilius emphasized the need for rapid action to build anti-drone defenses. Copenhagen is set to host an EU summit, and Sweden has offered its anti-drone technology to ensure the meeting proceeds without disruption. The Danish justice minister earlier noted the aim of such attacks is "to spread fear, create division and frighten us."
