In pictures: Scotland's four-day battle with wildfires

Firefighters and volunteers have been tackling incidents since Saturday.

Firefighters are at the scene of wildfires on moorland in the north of Scotland for the fourth day in a row.

There have been multiple incidents in the Highlands and neighbouring Moray since Saturday, when a blaze broke out on Dava Moor, just north of Grantown-on-Spey.

Scottish Fire and Rescue Service (SFRS) crews have also tackled fires near Carrbridge, and an incident that started on Monday morning in the Dallas area near Forres.

SFRS said eight fire appliances were at various locations to extinguish pockets of fire from Nairn in the Highlands to Knockando in Moray on Tuesday.

The fires have broken out in areas of moorland and forestry.

Deputy Assistant Chief Officer Ross Robison said: "The vast scale of these fires has been challenging for our crews over the past four days, particularly because of the strong winds that have caused the fires and smoke to spread further across the landscape.

"There has been a significant deployment of resources to the area, including on call and wholetime crews from Aberdeenshire, Moray and Highland who have been working effectively alongside landowners and partner agencies."

He added: "I'd like to recognise the efforts of all firefighters who attended and particularly those who are on call and often combine this role with other jobs in the community."

Fire crews from across Scotland have been called in

BBC Weather Watchers have reported smoke from a wildfire near Carrbridge in the Highlands drifting for 40 miles (64km) across the Moray Firth.

But residents in Orkney have also reported smelling smoke carried miles north on the wind.

Moray Scottish Greens councillor Draeyk Van Der Horn also photographed smoke from a number of wildfires visible from a summit in the Cairngorms on Monday morning.

The incidents have come during several days of dry, warm weather but there was heavy rain overnight.

The cause of the wildfires are not yet known, but Cairngorms National Park Authority has issued advice to people not to light campfires or use disposable barbeques.

On Monday, a number of local roads were closed due to drifting smoke.

Residents of Grantown-on-Spey, Carrbridge and Aviemore were advised to keep windows of homes and businesses closed because of the smoke.

A helicopter has been used to waterbomb some of the fires.

Reporting from Dallas on Tuesday, BBC News reporter Ben Philip said: "The extent of the damage today can be seen clearly.

"A large area has been affected with black burnt out vegetation stretching beyond the horizon.

"There's still a pungent smell of smoke. Many areas are still smouldering."
