Finland has raised alarms about a potential violation of its territorial waters by a Russian vessel in the eastern Gulf of Finland, prompting an investigation by the Finnish Border Guard. The incident, reported by the Finnish defense ministry, occurred on Friday and follows a recent pattern of incursions by Russian military assets, including a previous breach involving four military planes entering Finnish airspace in June. The Finnish government has not yet clarified whether the vessel involved is civilian or military. As tensions between Finland and Russia have escalated since the latter's invasion of Ukraine in 2022, this investigation reflects ongoing concerns regarding hybrid warfare tactics aimed at undermining national security. More information is expected to be released as the investigation unfolds.
