It's too early to say who is behind the latest drone incidents that have disrupted air traffic over Jutland.

Several airports have been affected - but significantly one of those airports in Aalborg is close to a military base, and a second airbase at Skrydstrup also reported drone activity. This is where some of Denmark's fleet of Denmark's F-16 and F-35 fighter jets are based.

The drone incident that closed Copenhagen airport on Monday night was already an alarm call - and prompted Denmark's prime minister to speak of “the most serious attack on Danish critical infrastructure to date".

The latest incidents are far more widespread and Danes are now raising questions about their air defences.

Russia has denied involvement in the Copenhagen incident, but there are further concerns now that Denmark is being subjected to hybrid warfare.

This is not the first Danish airport closure as a result of drones this week - Copenhagen airport was forced to close as a result of drones entering its airspace on Monday.

Authorities said that two to three large drones were spotted which suspended take-offs and landings for around four hours.

Danish police couldn’t confirm the type or the number of drones seen around the capital’s airport, but on Tuesday told reporters they were likely flown by a "capable operator" who wanted to "show off".

Asked by reporters on Monday if the drones were of Russian origin, Deputy Police Inspector Jakob Hansen said he could not confirm or deny this. Prime Minister Mette Frederiksen said Russian involvement could not be ruled out

Later on social media, Ukrainian President Volodymyr Zelensky referenced "Russia's violation" of Nato airspace in Copenhagen on 22 September, but did not indicate a source for the information.

Around 20,000 passengers were affected by the airport’s closure.

• Aalborg airport in the north of Denmark was temporarily closed after drones were seen in its airspace
• At least three flights were diverted away from Aalborg
• The Danish Armed Forces were affected as the airport is also used as a military base
• Three other smaller airports in the southern region - Esbjerg, Sønderborg and Skrydstrup - also reported drone activity, but were not closed
• North Jutland Police says it is monitoring the situation at Aalborg closely but did not say how many drones were involved
• Police do not believe there is any danger to passengers at the airport, or residents, but have asked the public to keep their distance

There's plenty we don't know - but as a reminder, a news conference is due to start in three minutes' time.
