Denmark, a founding member of NATO, has added to growing alarms about the threat of “hybrid war” from Russia as drone sightings spread to more European airports and even military installations.
On Thursday, the airport in Munich, Germany, grounded flights after several drone sightings. And on Friday, Belgium said it was investigating drone sightings above a military base near the German border. That’s after Denmark also reported drones flying above its airports and largest military base.
