Denmark has announced a total ban on civilian drone flights ahead of the scheduled visit of European Union leaders on Wednesday.
The visit is expected to focus on alleged violations of European airspace by Russia, which have raised serious security concerns across the continent.
Meanwhile, Germany has ordered its military to shoot down and destroy any suspicious drones that might appear during this period, according to international media reports.
These strict security measures come as NATO and EU countries remain on high alert following a wave of Russian drone incursions in recent weeks.
