Russian frigate fires flares near Danish helicopter in Baltic Sea

A Russian frigate fired two emergency flares near a Danish military helicopter on September 15, 2026, during a routine photographic surveillance mission in international waters off Gedser in southern Denmark. One flare passed within metres of the Fennec helicopter, according to Danish armed forces. The incident prompted Denmark to summon Russian Ambassador Vladimir Barbin and sparked diplomatic protest from Danish and European officials.

Denmark's Foreign Minister Lars Lokke Rasmussen described the action as "completely unacceptable" and said it endangered human lives. Prime Minister Mette Frederiksen branded it "reckless" and characterized it as part of a pattern of Russian hybrid warfare and testing of NATO resolve. European Commission President Ursula von der Leyen described Russia's behaviour as "reckless and dangerous" and linked the incident to broader patterns of Russian aggression in Europe. Danish Defence Minister Jeppe Bruus told Reuters that no attempt to make contact with the helicopter had been made by the frigate's crew, and he accused Russia of "deeply unprofessional seamanship." Denmark stated it would not invoke NATO Article 4 (consultations) or Article 5 (collective defence) over the incident.

Russia disputed the Danish account. Ambassador Barbin said the Danish helicopter conducted "provocative actions" and "dangerous manoeuvres" near the Russian warship, and that the communication problem lay with Denmark rather than Russia. He stated this was not the first such incident, referencing a similar complaint made the previous year involving the Russian warship Vice-Admiral Kulakov. Barbin noted that Denmark had declined Russia's repeated proposals to sign an agreement to prevent incidents at sea or in the air, and said Russia would "thoroughly investigate all the circumstances of the incident."

The flares used are pyrotechnic devices typically employed as maritime warning signals. The incident occurred amid elevated regional tensions, with NATO aircraft also shooting down an unidentified drone over Lithuania on the same night. The Baltic Sea and its straits remain a strategically sensitive area, serving as a major shipping gateway and key oil route.
