According to Kimmo Kohvakka, head of rescue services at Finland’s Ministry of the Interior, at least one drone entered Finnish territory. The aircraft was believed to be heading toward an area between Helsinki and the southern city of Porvoo, where the Neste Oyj oil refinery is located. Finland’s defense forces raised their combat readiness level in response. Finnish Air Force Hornet fighter jets were scrambled over the Uusimaa region, which includes Helsinki, and along the country’s southern coast. Air traffic at Helsinki-Vantaa Airport was restricted, while vessels in the Gulf of Finland were rerouted. Several flights arriving from Asia – including from Tokyo, Osaka, Hong Kong and Singapore – were diverted to alternate airports in Stockholm and the northern Finnish city of Rovaniemi. Authorities also delayed several routes, including a connection to Berlin via Tallinn. Nearly 2 million residents in southern Finland received emergency instructions early in the morning advising them to remain indoors and stay away from windows due to the drone threat.
