Unidentified drones once again entered Danish airspace on Wednesday night, forcing the temporary closure of Aalborg airport. Further drone activity was reported near at least three other locations, including military bases.
As we previously reported, Copenhagen airport in Denmark and Oslo airport in Norway were shut down earlier this week after similar drone incidents caused major travel disruption. Denmark’s justice and defence ministers now openly describe these events as part of a “systemic hybrid attack” against the country.
“There can be no doubt that everything points to this being the work of a professional actor when we are talking about such a systematic operation in so many locations at virtually the same time,” Defence Minister, and Deputy Prime Minister of Denmark Troels Lund Poulsen told reporters, calling the situation “a hybrid attack using different types of drones.”
Police added that Aalborg airport’s closure also impacted the armed forces since the facility serves as a military base.
Responding to questions from journalists, the ministers stressed there is no evidence linking the incidents directly to Russia, though they noted that other cases in Europe—including recent accusations by Poland, Estonia, and Romania of airspace violations, which Moscow has denied—have been attributed to Russia.
For now, Denmark is only considering requesting NATO Article 4 consultations, with no decision yet taken.
NATO’s Article 4 does not call for military action but requires allies to consult whenever a member believes its security or territorial integrity is at risk.
