The fire service in Surrey has declared a major incident as crews battle an open fire.
Writing on Twitter, the Surrey Fire and Rescue said: “We have several fire engines in attendance.
“There is a great deal of smoke so please avoid the area, windows and doors should be closed if nearby and pets kept indoors. More info to follow.”
The fire is at Hankley Common near Farnham, with pictures on social media showing smoke filling the sky as far away as Guildford.
It comes after a swathe of wildfires in London and the surrounding area after last weeks record temperatures left the ground tinder-box dry.
