A man died when a truck and a van collided on Finland's National Road 4. Authorities said no one else was injured in the crash. The report did not specify where along the highway the accident happened or at what time. National Road 4 is the country's longest trunk road, running from Helsinki all the way north to Lapland. Collisions between heavy lorries and smaller vans tend to be serious because of the difference in size and weight. Police have not yet released details on what caused the two vehicles to collide.
