Russia summons Danish ambassador over Baltic Sea warship encounter

Diplomatic protest in Moscow

The Russian Ministry of Foreign Affairs summoned Denmark's ambassador Rolf Holmboe on 30 September to lodge a formal protest over a maritime incident in the Baltic Sea. Russian officials presented what they described as an energetic protest against maneuvers carried out by a Danish Air Force Fennec helicopter near the Russian naval vessel Soobrazitelny. The confrontation took place on 14 September in neutral waters in the south-western Baltic Sea, south of the Danish island of Falster. Moscow asserted that the aircraft conducted unprofessional and provocative actions that created direct risks for maritime navigation. The diplomatic move followed weeks of friction after Danish authorities made their own official complaints about the encounter.

Competing versions of the Baltic encounter

Danish and Russian authorities offer conflicting accounts of what occurred during the interaction between the helicopter and the warship. Danish military officials stated on 15 September that their helicopter was conducting a routine photographic mission when the Russian vessel fired two signal flares without prior radio contact. According to Copenhagen, one of the flares passed within close range of the aircraft. In contrast, the Russian Foreign Ministry claimed the helicopter flew at a dangerous altitude and hovered less than 50 meters above the vessel, creating hazards of collision and technical interference. Russian officials maintained that their crew issued multiple radio warnings on international frequencies before launching flares away from the aircraft to draw its attention.

The Russian Foreign Ministry issued a statement outlining its account of the warning signals.

All warnings about the dangerous altitude of the helicopter, transmitted repeatedly by the Russian crew on international frequencies, were ignored. To draw attention, the corvette fired two flares in the opposite direction from the helicopter, after which it ceased its provocative actions and left the area near the ship.

Danish diplomatic reactions and timeline

The encounter prompted swift political condemnation in Denmark when it first occurred in mid-September. The Danish Ministry of Foreign Affairs summoned Russian Ambassador Vladimir Barbin on 15 September to protest the firing of flares against its aircraft. Danish Prime Minister Mette Frederiksen described the Russian warship's actions as reckless against an aircraft operating on a routine flight. Danish Minister of Defence Jeppe Bruus categorized the conduct as extremely unprofessional and confirmed that the Russian ship did not attempt communication prior to firing. Danish Foreign Minister Lars Løkke Rasmussen designated the event as unacceptable and stated that human lives were placed at risk.

Baltic security and regional strains

The diplomatic confrontation reflects ongoing strains across the Baltic Sea between NATO members and Moscow. The Russian Foreign Ministry rejected Denmark's claims as unacceptable and warned that growing NATO military activity in the Baltic region could lead to escalation and severe incidents. Relations between Copenhagen and Moscow have deteriorated steadily following Denmark's extensive military and political support for Ukraine since 2022. NATO member states have simultaneously increased their military presence along their eastern borders to counter hybrid threats attributed to Russian intelligence services. European Commission spokesperson Christian Wigand noted on 29 September that security threats near European Union borders have grown more frequent, following accusations from Estonia regarding a Russian arson attack against a domestic drone manufacturer.
