Forest fires have gripped the UK countryside threatening homes, flora and wildlife as most people enjoyed the hot, dry Bank Holiday weather.
Extra helicopters were drafted in to help fight fires
Dramatic wind changes could force firefighters in Ayrshire, Scotland, to evacuate homes as a rapidly-spreading fire, which started on Thursday and covers 12 square miles, continues to burn near Darvel.
In south Wales, dozens of houses and a children's home in Gwent were evacuated overnight as firefighters battled a blaze.
On Thursday, five people had to be rescued by helicopter after they became trapped in a forest and heath fire in Dorset.
The outbreak of forest and moorland fires prompted calls for greater care by people enjoying the Bank Holiday heat wave.
Firefighters in Ayrshire, who have been working round the clock, have been joined by crews from neighbouring Lothian and Borders and Dumfries and Galloway.
A third helicopter is being brought in from Devon to drop water on the fire.
Strathclyde Fire Brigade's assistant firemaster, Phil Robinson said: "It is a very difficult type of fire to fight because of the weather conditions, the dryness and the vegetation.
"The weather is so hot and everything is so dry it could have been started by a cigarette end or anything.
"Being one of the largest brigades in Europe we are able to cope with this but it really is stretching our resources."

Mr Robinson said the blaze was not endangering homes at the moment, but given the wind direction and
speed of the fire, that was a potential threat.
"If any homes are likely to be involved, they will be evacuated long before there is any danger to life," he said.
Farmers using quad bikes were out in the moorlands trying to rescue sheep.
A large blanket of smoke hovered over the nearby village of Darvel, in stark
contrast to the surrounding clear blue skies.

Willie Cairns, of the Forestry Commission, urged people to be more careful.
He said: "Go out and enjoy yourselves but take care of things that can be set alight - it is no more than common sense.
"Extinguish matches properly, be careful with barbecues and take rubbish home with you because even a small piece of glass if hit by the sun in the right way can cause a fire."
