Denmark slapped a nationwide ban on civilian drone flights Monday through Friday, a stark security pivot to safeguard an upcoming EU defense summit amid a rash of mysterious UAV sightings over airports and bases, as Prime Minister Mette Frederiksen pointed fingers at Russia without hard proof.

The transport ministry, via Minister Thomas Danielsen, framed the measure as a police aid to sift threats from hobbyists: "We cannot accept foreign drones creating uncertainty."

It kicks in ahead of Wednesday's EU Council on defense and Ukraine, plus Thursday's European Political Community gathering, where top brass from 47 nations converge—drawing heightened NATO eyes after last week's closures at Copenhagen, Oslo, Aalborg, and Billund.

Unexplained drones buzzed military sites Saturday, capping a week of disruptions that stranded thousands; investigators eye a "hybrid attack" in a "systematic operation," per Defence Minister Troels Lund Poulsen, though Moscow rejects involvement outright. Frederiksen hedged: "There is predominantly one country that poses a threat... Russia," while allies like Germany and Sweden pledge anti-drone tech—radar, optics, acoustics—for Baltic bolstering via the Sentry mission.

The clampdown, punishable by fines or two years' jail, ripples as Europe frets incursions: Russian drones pierced Polish and Romanian skies, MiG-31s Estonian airspace, prompting 10 EU ministers to ink a "drone wall." Norway and Romania logged weekend flaps too, fueling calls for shared vigilance without pinning culprits.

As Copenhagen preps for leaders, the blackout tests hybrid defenses in a jittery continent, where cheap tech sows doubt—Russia decries the blame game, Denmark doubles down on caution, and citizens clip wings for the greater guard.
