Arlanda Airport in Sweden was temporarily closed after four drones were spotted flying over the area, prompting authorities to halt all air traffic.

The incident occurred late at night, leading to several flights being redirected to other airports, including Skavsta and Landvetter.

The Swedish Civil Aviation Administration made the decision to close the airport as a precautionary measure.

Police have launched an investigation into potential airport sabotage and violations of the protection law.

The drones were pursued by helicopters and police patrols, but it remains unclear if they were neutralized or left the area on their own.

Air traffic resumed a few hours later, but the incident has raised concerns about airport security and drone regulations.
