Several flights were diverted after reports of several drones at Gardermoen outside Oslo.

– Nothing has been confirmed. In any case, we have to take this seriously, says operations chief Gisle Sveen in the Eastern Police District to NTB.

The pilot who raised the alarm believed he had seen between three and five drones during approach to the airport.

By 01:30 the airport was back in operation.

Just over two weeks ago, the airport was closed for several hours after a drone alert.
