• Police are investigating alongside the armed forces and intelligence services after deciding not to shoot down the drones to protect civilians.
• Officials described a professional, coordinated pattern and announced new detection and counter‑drone tools, while noting no confirmed link to Russia as Moscow denies involvement.
• NATO and EU leaders said they take the incidents seriously, with NATO’s secretary‑general speaking to Prime Minister Mette Frederiksen about protecting critical infrastructure.
• Air travel was disrupted with diversions and delays affecting carriers including SAS, Norwegian and KLM, and Norwegian police separately seized a drone near Oslo with no link seen to the Danish cases so far.
