Denmark's Prime Minister links drone incursion at Copenhagen airport to possible Russian involvement, citing recent similar incidents in Poland, Romania, and Estonia. The motive behind the drone sightings was likely to disrupt and test limits, causing unrest. Norwegian Oslo airport also faced drone sightings, raising concerns over airspace security.
