COPENHAGEN, Sept 23 — Copenhagen airport was closed yesterday after unidentified drones were observed nearby, causing around 15 flights to be diverted, police and airport officials told AFP.

“The airspace over Copenhagen airport has been closed since 8:30pm (1830 GMT) due to two to three unidentified drones. No aircraft can take off or land,” airport spokesman Lise Agerley Kurstein said.

She said around 15 flights had been diverted to other airports.

Copenhagen police meanwhile said “three or four big drones” had been observed flying over the airport.

“They are still flying back and forth, coming and going,” duty officer Anette Ostenfeldt told AFP at 10:45pm (2045 GMT), adding that police were at the airport investigating.

She could not say if the drones were military or civilian devices.

“But they are bigger than what you as a private individual can buy,” Ostenfeldt said.

Airport officials said the airport would remain closed until the situation was resolved.

“We currently have no timeline for reopening,” Kurstein said. — AFP
