Denmark launches extensive investigation into monitoring unidentified drones flying over four airports.

Danish police announced that drones of unknown origin were spotted on Wednesday night over four of the country’s airports, causing one of them to be closed for several hours.

The drones were observed flying over Aalborg (north), Esbjerg (west), Sønderborg (south) airports, and Skrydstrup Air Base (south), before leaving these locations.

Denmark’s Airports

This security breach comes after drones of unknown origin flew over Copenhagen Airport, as well as over Oslo Airport in neighboring Norway, disrupting air traffic at both for several hours.

According to police, this breach on Wednesday led to the closure of Aalborg Airport, located in northern Denmark and considered one of the country’s largest airports after Copenhagen, before it was reopened after several hours.

A senior inspector stated that regarding the incident at Aalborg Airport, “it was not possible to shoot down the drones that flew over a very wide area for two hours. Furthermore, we have not yet been able to apprehend their operators.”

Unidentified Drones

For its part, the South Jutland Police said it “received several reports on Wednesday night about drone activity at Esbjerg, Sønderborg, and Skrydstrup airports.”

Esbjerg and Sønderborg airports were not closed because there were no scheduled flights there before Thursday morning.

Danish police explained in their statement that these drones “were flying with lights and were spotted from the ground, but their type… or motives are not yet clear.”

Extensive Investigation

They added that they are “conducting a wide-ranging investigation in cooperation with the Danish intelligence service and the armed forces to clarify the circumstances” of this breach.

The Prime Minister had said on Tuesday that the country had witnessed “the most serious attack on vital Danish infrastructure.”

This followed the flight of large drones over Copenhagen Airport, which caused its closure for hours.
