Several drones might have entered Finland: NBI

The authorities do not completely exclude the possibility that, in addition to the unmanned aerial vehicles already found in Finland, several other such aircraft might have ended up in the country, said the National Bureau of Investigation (NBI) on Thursday based on information gathered during the investigations.

The NBI and the Border Guard have continued to investigate the unmanned aerial vehicles which entered Finland and fell on the ground on 29 March 2026, and the unmanned aircraft found on 31 March 2026.

The authorities have carried out forensic investigations and gathered background information to investigate the incidents.

The investigations continue at Easter. It is suspected that the unmanned aircraft under investigation are of Ukrainian origin.

The Southeastern Finland Police Department continues to verify the sightings of unmanned aircraft. The Border Guard investigates the incidents as territorial violations.

“We have continued the investigation of territorial violations by examining the extensive criminal investigation material. Cooperation between the authorities has been excellent in the case,” said Senior Lieutenant Jyri Siitari of the Gulf of Finland Coast Guard, who heads the investigations into the territorial violations.

The offences investigated by the NBI are grossly negligent endangerment and negligent endangerment. The Finnish Defence Forces have provided assistance in the investigations.

“Based on information gathered during the investigations, we cannot at this point completely exclude the possibility that, in addition to the unmanned aerial vehicles already found, other unmanned aircraft might have also ended up on the ground during the previous incidents,” said Deputy Director of NBI Timo Kilpeläinen.

Because of the Ukrainian response to the Russian war of aggression, it is possible that such aircraft might also be strayed into Finnish territory in future, especially in the area of Kymenlaakso and South Karelia.

One more Ukrainian drone was found in Finland on March 31, 2026.

Earlier, two drones crashed in Kouvola in southeastern Finland after entering into Finnish airspace in the morning on March 29.

The Finnish Defence Forces intensified surveillance measures to ensure territorial integrity when Ukraine carried out attacks against Russian targets in the eastern Gulf of Finland.
