The ministry said in a statement that it had “several capacities deployed” after drone sightings from Saturday into Sunday night. This is the latest unexplained drone activity after several sightings, including over five Danish airports last week, raising concerns about security in northern Europe amid suspected growing Russian aggression. Tensions have been running high in Denmark in recent days following reports of drone activity, and hundreds of possible sightings reported by concerned citizens that couldn’t officially be confirmed. While it’s not clear who is behind the drone activity, Denmark’s prime minister and NATO’s secretary-general said last week that Russian involvement couldn’t be ruled out. No,” he said, asking whether NATO would shoot down his helicopter when flying close to the Polish border.
