Fresh incidents and emergency measures

Denmark said drones were sighted again overnight above several armed forces locations, days after similar activity disrupted airports. Authorities have tightened security around key installations and are coordinating with NATO partners while investigations continue. Officials have not assigned blame but described the pattern as consistent with hybrid interference. The incidents come as Copenhagen prepares to host high-level European gatherings, raising the stakes for airspace control and critical-infrastructure protection. Civil aviation remained normal Sunday, though contingency plans were readied in case of additional sightings.

Regional context and risk calculus

Nordic and Baltic states have faced periodic airspace incursions and suspected sabotage since Russia’s full-scale invasion of Ukraine. Denmark’s defense ministry is weighing temporary restrictions on civilian drone flights near sensitive zones and bolstering counter-UAS capabilities, including radar coverage and signal disruption tools. Security analysts say attribution may take time, but even unclaimed flights can create outsized disruption by forcing shutdowns and diverting resources. For ordinary travelers and nearby communities, the near-term question is whether authorities can deter copycat flights while keeping airports and seaports open during a busy diplomatic week.
