A wildfire apparently started by a single dropped cigarette is still burning and fire crews remain on the scene.

Scottish Fire and Rescue Service crews were sent to Ben Lomond yesterday to tackle a blaze on the mountainside.

A line of flames stretched to a distance of around one kilometre at the fire’s height on Tuesday.

The National Trust for Scotland confirmed firefighters remain on the scene as of Wednesday morning.

In a tweet, the heritage body said the fire had calmed significantly since Tuesday but it was not yet put out.

The Trust said: “Thanks to everyone for their support and concern about the wildfire on Ben Lomond.

“Fire intensity has decreased substantially overnight, but it is not yet extinguished.

“The Scottish Fire and Rescue Service are onsite this morning.

“We're very grateful for everyone's understanding at this time and ask people to please continue to avoid the area for now.”

It is not thought anyone has been injured by the fire.
