It is currently unclear whether the events have any connection to each other, but Norwegian and Danish authorities are cooperating to see if there is any connection.
The drones over Copenhagen Airport disappeared on their own, says Jakob Hansen at the Danish police during a press conference on Tuesday night.
We are now conducting an intensive investigation to find out where the drones are from, their activity and so on, he says.
It is currently unclear what type of drones it is.
No person on any flight or similar has been in danger.
At the same time, flights on their way to Oslo Airport are circling over the city waiting for rerouting, says the airport's communications manager Monica Fasting to VG.
Earlier in the evening, two foreign nationals were arrested in the Norwegian capital after a drone had flown into a prohibited zone in the military area at Akershus fortress.
There is no information about drones at any Swedish airport.
”We can confirm that we have received flights that have been rerouted from Copenhagen to Malmö and Gothenburg Landvetter this evening”, writes Ellen Laurin, deputy press manager Swedavia, in an email to TT.
