Two days after the  drone sightings in Copenhagen and Oslo, Denmark reported further drone sightings at several airports in the country. The Danish government and German Interior Minister Alexander Dobrindt are calling it a  "hybrid attack ." Defense Minister Troels Lund Poulsen stated that it appears to be the work of a professional actor. The drones appeared simultaneously in several locations and  disrupted air traffic in Aalborg and, previously, in Copenhagen. Denmark's Prime Minister Mette Frederiksen had previously described the attacks as  "the most serious attack on Danish critical infrastructure to date." Hans-Jakob Schindler is a security expert at the Counter Extremism Project. In this podcast, he explains who might be behind it and why Denmark, of all places, was targeted.
