Up to 40 firefighters have worked through the night to tackle a major fire at a woodyard.
Crews were called to the scene at Anderson's woodyard, Bo'ness, near Falkirk, at around 10.40pm on Wednesday.
They found a large quantity of compacted sawdust ablaze at the Haney's Way business.
At the height of the incident, 40 firefighters were involved in tackling the blaze, Central Scotland Fire and Rescue Service said.
Six fire engines, an incident command unit, a water-carrying vehicle and an aerial ladder platform were also used in the operation.
The fire service said the cause of the blaze is not yet known and an investigation will be carried out.
Crews remain at the scene on Thursday morning and are still working to put out the flames, a spokesman confirmed.
He said: "The cause of the fire is unknown and a full fire investigation will take place when the fire has been extinguished. Crews are expected to remain on scene for some time."
