COPENHAGEN - Copenhagen airport was closed on Monday 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 due to two to three unidentified drones. No aircraft can take off or land," airport spokeswoman 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, 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.
