A passenger train has derailed near the eastern Scottish town of Stonehaven, killing three people and injuring several others.
The accident, which occurred Wednesday morning on a steep wooded slope south of the city of Aberdeen, left several carriages overturned and piled on top of each other, making it difficult for emergency services to reach the scene.
Dark smoke could be seen billowing from the area for most of the day after the ScotRail train derailed.
Aerial footage showed one carriage detached from the rail tracks and lying on its side some distance down the slope. Another was completely overturned and had two carriages resting on it, one of which was also overturned.
Two air ambulances and about thirty emergency service vehicles could be seen in a field just above the site. With rescue workers hampered by the steep terrain and dense woodland, it took many hours for casualty numbers to be confirmed, a Reuters report said.
The British Transport Police said the driver was believed to have been among the dead. Six people were taken to hospital with injuries not thought to be life-threatening. Everyone who had been on board the sparsely-populated train was accounted for, according to a police spokesman.
The police gave no indication on the causes of the accident, saying only that it was investigating.
But some reports have suggested that a landslide may have played a significant part.
In recent days, Stonehaven and the surrounding area has been hit by floods following heavy rains.
