Denmark has banned all civilian drone flights from Monday to Friday due to recent drone sightings at military facilities, especially ahead of the EU Summit in Copenhagen. The ban aims to prevent confusion between enemy and legal drones. Violations can lead to fines or imprisonment. Military and emergency drone operations are exempt. NATO is enhancing vigilance in the region, and Germany is providing military support. Tensions are high due to previous drone sightings causing airport shutdowns, with potential Russian involvement suggested.
