The Danish Armed Forces announced that military personnel spotted drones near several army facilities during the night of 28 September, according to an official statement from the force.

“Several units were deployed to counter them,” the Armed Forces reported, though no details about the incident were disclosed.

This marks the second consecutive night of drone activity over Danish military installations. Unidentified drones were observed near military facilities on the night of 27 September, following several intrusions near airports and critical infrastructure throughout the week.

The incidents are part of a broader pattern of airspace violations across Europe that began in late August, with unknown drones flying over local airports in various countries.

The situation escalated on the night of 10 September when Russia launched another drone and missile attack on Ukraine. Several Ukrainian drones entered Polish airspace, prompting Polish aircraft to use weapons against them for the first time. Polish Prime Minister Donald Tusk stated that Poland’s airspace had been violated at least 19 times.

On 13 September, Romanian F-16 fighters detected a drone in national airspace and tracked its movement to approximately 20 kilometers southwest of Chilia Veche commune until it disappeared from radar.

Three Russian MiG-31 fighters entered Estonian airspace on 19 September and remained there for 12 minutes. The same day, Poland’s Border Guard reported that two Russian fighters violated the security zone of the Petrobaltic drilling platform in the Baltic Sea.

NATO responded by launching the “Eastern Guardian” initiative to strengthen defense of Europe’s eastern flank, including the deployment of ground forces in eight countries.
