A Russian Navy frigate fired two pyrotechnic flares toward a Royal Danish Air Force AS-550 Fennec helicopter on Monday, with one flare passing within a short distance of the aircraft, according to an official Danish Armed Forces statement released late Monday. No injuries or damage were reported. The incident occurred in international waters south of Gedser, on the Danish island of Falster, while the helicopter conducted a routine photographic reconnaissance flight over the frigate, a standard NATO practice for monitoring foreign naval vessels in the Baltic Sea.
Danish Defense Minister Jeppe Bruus confirmed to broadcaster TV2 that Denmark has formally summoned the Russian ambassador in Copenhagen to demand an explanation. Prime Minister Mette Frederiksen called the act "completely unacceptable" on Tuesday morning, writing on X that it was "part of the pattern we see throughout Europe" and warning that "Russian actions are meant to intimidate and divide. They will not succeed." As of this writing, no Russian government statement has addressed the incident.
What is confirmed, what is not
Danish defense researchers describe the flares as pyrotechnic warning signals rather than offensive weapons, and have characterized the firing as intended to force the helicopter to keep its distance. Denmark's government is nonetheless treating the act as reckless. Foreign Minister Lars Løkke Rasmussen said the incident "could have endangered human lives," adding that "Russia is gradually moving the line for what it considers acceptable behaviour." The identity and class of the frigate have not been publicly confirmed, nor has Russian intent, whether this was a deliberate provocation, a standard warning procedure, or a local command decision. Former Defense Minister Troels Lund Poulsen called it further evidence of "extremely aggressive" Russian behaviour seeking to "provoke potential conflicts," a characterization not yet corroborated by an official Danish investigation.
The same day, NATO fighter jets shot down a drone over Lithuania, the country's National Crisis Management Centre said, according to national broadcaster LRT. Preliminary data indicated the drone originated in Belarus and fell near Lake Kaunas. President Gitanas Nauseda confirmed the shootdown on X.

The straits that cannot be closed
The Danish straits remain the principal maritime gateway into and out of the Baltic Sea, used by commercial and military traffic alike. The Russian frigate had a legal right to transit; the Danish helicopter had a legal right to observe it. What changed Monday, according to Copenhagen's own characterization, is that a routine encounter became a hostile one. Defense Minister Bruus has summoned parliamentary party representatives for a briefing at the defense ministry. Moscow has yet to respond.
