Three people have been stabbed to death by a man who hijacked a bus on a remote mountain road in central Norway.
Emergency services were called to what they thought was a traffic incident between Aardal and Tyin, about 220 kilometres northwest of Oslo.
Firefighters, the first to arrive on the scene, detained the man until police arrived.
The motives of the hijacker, in his 50s, were not immediately clear, police said.
