No details were available about the cause of the crash, which occurred "in the Rovaniemi airport area" around 11:00 am (0800 GMT), the military said.

Dark smoke could be seen rising from the scene and several emergency vehicles were dispatched to the area, public service broadcaster YLE said.

The road leading to the airport was closed to traffic, and police blocked access to the airport, it added.

Airport operator Finavia told AFP that it did not expect civilian flights to be affected by the accident for the time being, with the next flight not expected for several hours.
