Police said one to two drones were observed on Friday at about 8.15 pm (7.15pm local time) near and over Karup airbase, the country's biggest base that houses all of the armed forces' helicopters, airspace surveillance, flight school and support functions. Karup is also home to parts of the defence command, according to the military's website. A police spokesperson, Simon Skelkjaer, said police could not comment on where the drones came from, adding: We didn't take them down.
"The drones have disappeared and the airport is open again," Deputy Police Inspector Jakob Hansen told reporters. "We didn't take the drones down," he added. The airport was closed for several hours before reopening early Tuesday, causing numerous delays and travel disruptions to 20,000 passengers, airport officials said. Hansen said police were cooperating with the Danish military and intelligence service to find out where the drones had come from.
