Three people have been killed and three injured after a runaway freight train crashed into a building at an industrial port in Norway, police said.
Local media said the train of 16 empty carriages had sped wildly for several kilometres before crashing in Oslo, the Norwegian capital.
The victims had been working in or around the building, which collapsed from the impact, a police spokeswoman said.
It was not immediately clear what caused the accident in the southeastern district of Sjursoeya on Wednesday.
Vegar Halveg, a local worker at the port, said he heard a loud screech and saw several empty cargo train cars speed past.
"They were going much faster than they usually do, so we realised something was wrong," he told the Associated Press,
"The last car was practically airborne," he said.
Several train cars also ended up in the water after crashing at the port.
Dozens of ambulances, several helicopters and a coast guard boat, along with other rescue workers, were sent to the scene, local media said.
