The Finnish Defence Forces implemented a temporary flight restriction zone over the eastern Gulf of Finland on Thursday morning at 4:26 AM local time. The reason for the restriction was not immediately specified, but it suggests heightened military activity or security concerns in the region. The no-fly zone impacted civilian and potentially military air traffic within the designated area. However, the restriction was lifted shortly after implementation, indicating a short-term and resolved situation. Details surrounding the cause and purpose of the airspace closure remain limited at this time. The Defence Forces have not yet released a public statement elaborating on the incident.
