Denmark has significantly heightened security measures in Copenhagen as European Union leaders convene for a critical summit on Wednesday. The move comes in response to escalating tensions following a series of Russian incursions into EU airspace and recent drone attacks targeting Danish airports. These incidents have particularly alarmed Eastern European nations such as Poland and Estonia, prompting ten EU member states to endorse a multi-layered ‘drone wall’ initiative aimed at detecting, tracking, and neutralizing Russian drones.
