Firefighters are on their way to a possible fire in a remote crofting township at the western end of the Ardnamurchan peninsula.
A fire service spokesman said they received a report of smoke coming from the roof of a property at Portuairk, near Kilchoan, in Lochaber, soon after 6pm.
He said three appliances were responding to the call – one each from Kilchoan, Strontian and Lochaline.
