Denmark Ramps Up Defenses as New Drone Suspicion Fuels Fears

Denmark is on heightened alert and stepping up its defenses before European leaders meet in Copenhagen this week, as a new suspected drone intrusion temporarily shut airspace and intensified security concerns.

An eight-minute closing of the airspace over Aalborg airport and air base on Tuesday morning due to potential drone activity shows how cautious authorities are after a week of near-continuous suspected sightings. The government has now also raised its threat level for the energy industry, imposing stricter security requirements on facilities.
