A Russian frigate fired two flares at a Danish military helicopter during a routine photographic mission in international waters off Denmark, with one flare passing close to the aircraft, Denmark’s armed forces said.

The incident comes amid a growing series of confrontational incidents involving Russia and NATO countries, as Western officials warn that Moscow is becoming increasingly willing to test the alliance’s defenses and intimidate its members.

Flare passed close to Danish helicopter

The Danish Fennec helicopter was conducting routine photographic coverage of the Russian frigate when the ship fired two flares at it, according to Denmark’s Armed Forces. The incident occurred off Gedser, at the southern tip of Denmark, on 14 September.

One of the flares passed close to the helicopter. The Danish military did not report any injuries or damage and said it had no further comment on the incident.

Flares are pyrotechnic devices normally used as attention signals at sea.

Danish Foreign Minister Lars Løkke Rasmussen called the incident “completely unacceptable” and said Russia’s ambassador had been summoned for talks.

Prime Minister Mette Frederiksen called it “reckless action from Russia towards Danish military” during a routine overflight, saying Russian actions were intended to “intimidate and divide.”

Russia’s ambassador to Denmark, Vladimir Barbin, disputed Copenhagen’s account, telling DR that Moscow would investigate and accusing the Danish helicopter of provocative actions near the Russian frigate.

Another incident in a growing pattern

The episode comes as Russia’s behavior toward NATO countries has become increasingly confrontational in recent months.

NATO fighters have repeatedly been scrambled over Russian military aircraft in the Baltic region, while European countries have dealt with airspace incidents, suspected Russian drones and other security threats linked to the war against Ukraine.

On 15 September, NATO aircraft also shot down a drone over Lithuania after it entered the country’s airspace from the direction of Belarus. The drone was believed to have been carrying an explosive device.

NATO spokesperson Allison Hart described the Danish incident as “another irresponsible Russian action” intended to intimidate the alliance, adding that NATO would continue defending its territory and supporting Ukraine.

The incidents are unfolding as Russia continues its full-scale war against Ukraine and expands pressure beyond the battlefield. Western officials have increasingly warned that Moscow is using military intimidation and other forms of pressure against European countries while testing how far it can push NATO without triggering a direct confrontation.

The flare incident comes amid a broader deterioration in European security, with Russian military activity increasingly creating dangerous encounters with NATO forces.
