The airport in the Danish capital Copenhagen has resumed operations after being closed a few hours ago due to drones being spotted in its area, Reuters reported, quoted by BTA.
"As a result of the closure of the airport for four hours, there will be delays and flight cancellations. Passengers are urged to check for possible flight changes," an airport spokesman said.
An investigation has been launched into the drone incident.
Due to the airport's closure, about 50 flights were diverted to other airports.
