Aalborg Airport in northern Denmark has been closed after unauthorized drones were spotted in its airspace, according to local authorities.

Three other smaller airports in the southern region of the country, Esbjerg, Sønderborg and Skrydstrup, also reported drone activity but were not closed.

The incident comes after the country's Copenhagen airport was forced to close earlier this week due to a drone intrusion, which the prime minister described as "the most serious attack on Danish infrastructure to date."

Police said the devices could be seen from the ground, adding that they could not rule out the possibility that the activity was a prank. They were investigating who was controlling them and their motive.

On Monday, Kastrup Airport in Copenhagen was forced to close for several hours after a number of drones were spotted.

"This says something about the times we live in and what we as a society need to be prepared to deal with," Prime Minister Mette Frederiksen told reporters.

Russian involvement cannot be ruled out, she added - although Kremlin spokesman Dmitry Peskov called the allegations "baseless".

At least three flights have been diverted from Aalborg airport, with officials saying the Danish Armed Forces were affected as the airport is also used as a military base.

North Jutland Police issued a statement saying they were closely monitoring the situation in Aalborg, but could not provide details on how many drones were involved.

"We still cannot comment on the purpose of the drones flying in the area, nor can we say anything about who the actor is behind this," said Chief Inspector Jesper Bøjgaard Madsen.

"If we are given the opportunity, we will shoot down the drones," he added.

Police said they did not believe there was any danger to passengers at the airport or residents, but asked the public to keep their distance from the area.

Referring to reports of drones in Esbjerg, Sønderborg and Skrydstrup, police said they were "taking the situation seriously" but could not comment on the motive.

They added that none of the airports had been closed and there was no risk to the public.

Of the three flights affected in Aalborg, two returned to Copenhagen and another to the town of Karup.

The agency that oversees European air traffic control said arrivals and departures at the airport would be suspended until 06:00 local time (04:00 GMT) on Thursday.

Europe has been on high alert after several NATO member states reported Russian intrusions into their airspace.

Last week, Estonia and Poland requested a consultation with other NATO members after Russia was accused of violating their airspace in separate incidents.

Romania, another NATO member, also said Russian drones had violated its airspace.

Russia denied violating Estonian airspace, while insisting the Polish incursion was not intentional. It did not comment on the incident in Romania.

After Tuesday's meeting, NATO issued a statement condemning Russia's actions and warned that it would use "all necessary military and non-military means" to defend itself.

"Russia bears full responsibility for these actions, which are escalating, risk miscalculation and endanger lives. They must stop," she said.

NATO Secretary General Mark Rutte said: “We are a defensive alliance, yes, but we are not naive, so we see what is happening.”

After his speech at the UN, Donald Trump suggested that NATO countries should shoot down Russian planes that violate their airspace./ CNA, translated by BBC
