Finland’s Ministry for Foreign Affairs confirmed on Monday it had summoned Russia’s ambassador to Helsinki following a suspected airspace violation by two Russian military aircraft last Friday.
The alleged breach occurred off the coast of Porvoo in southern Finland, prompting an immediate investigation by the Finnish Border Guard. “Finland takes this suspected territorial violation extremely seriously,” the ministry stated in an official communiqué to Reuters.
The protest comes as the Baltic Sea region remains on heightened alert following multiple infrastructure disruptions since Russia’s 2022 invasion of Ukraine.
NATO has meanwhile, significantly increased its maritime presence in the area, deploying additional frigates, surveillance aircraft and naval drones to protect critical undersea cables and pipelines. Russia’s embassy in Helsinki had yet to respond to requests for comment at time of publication.

The Regional Security Implications Following Finland’s NATO Accession
This incident marks the first major airspace dispute between Finland and Russia since Helsinki joined NATO, ending decades of military non-alignment.
Security analysts note increasing Russian military activity near Nordic borders, with similar airspace violations reported by Sweden and Estonia in recent months. The Porvoo region holds particular significance as it lies near crucial Baltic shipping lanes and energy infrastructure.
The airspace violation investigation coincides with ongoing concerns about the security of undersea cables and pipelines in Northern Europe. Since 2022, the Baltic Sea has experienced multiple incidents involving damaged gas pipelines (Nord Stream) and telecommunications cables, with NATO establishing a dedicated critical undersea infrastructure protection force in response.
Finland’s foreign ministry has however, emphasized its commitment to defending both territorial integrity and regional energy security through enhanced NATO cooperation.
Finnish officials have also pledged to maintain open channels with Moscow while working closely with NATO allies to monitor all border areas. The Border Guard’s investigation into Friday’s incident continues, with results expected to inform Finland’s ongoing air defense strategy adjustments.
