Crews tackling wildfire near Land's End Airport
Firefighters are battling a blaze that has sent thick plumes of smoke into the sky near an airport.
The wildfire in the St Buryan area, near Land's End Airport, ignited at about 12:20 BST, Cornwall Fire and Rescue Service said.
A spokesperson for the airport said the airport was temporarily closed and "passengers and employees are being moved away from the site".
Sarah Torr, who is nearby with husband Simon, said: "To start with we could just see smoke. Now we can see a wall of fire."
She said a cloud of black smoke about 300-400m wide was "hanging over west Cornwall".
Simon TorrCornwall Fire and Rescue Service said initial crews requested further help on arriving in the hamlet of Crows-An-Wra.
It said: "In total four appliances are currently in attendance/on their way to this incident."
Cornwall Council said on Facebook there was "a lot of smoke in the area" and people were urged to avoid the area and keep windows and doors closed.
A spokesperson for Land's End Airport said: "We are aware of a fire near Land's End Airport, being managed by emergency services.
"As a precaution, the airport is temporarily closed and passengers and employees are being moved away from the site."
Simon TorrResidents across Devon and Cornwall are being urged to avoid carrying out controlled burns after a number of other fires in the last 24 hours.
On Tuesday, fire crews tackled two separate wildfires in Cornwall, one at Mawgan Porth and the Porth area of Newquay, with residents being urged to keep doors and windows closed because of a smoke plume.
Cornwall Fire and Rescue Service also said a wildfire in Carnmarth, near Lanner, had four appliances sent to tackle it.
Firefighters in Devon also tackled a grassland blaze in Mincinglake Valley Park that caused several people to flee their homes. Officials said on Wednesday morning that crews were still "on scene monitoring and dampening down hot spots".

A large fire was also reported at Advent, Camelford, at about midnight on Wednesday.
Devon Wildlife TrustDevon Wildlife Trust said the fire at Mincinglake Valley Park had been devastating and that it would take "a number of years" for wildlife to recover.
Land manager Matt Boydell said it was "pretty devastating".
He said: "The elements of the grassland and some of the scrub has been lost, but those are the elements that do come back quicker.
"Luckily, from a very quick look, it looks as though some of the sort of larger trees haven't had too much damage, which is a real relief because, obviously, those are the elements that take decades to return.
"The amazing thing with wildlife is, if you give it space and you give it time and some support, it will recover and it will recover back to what it was."
Labour Exeter City Council member Liz Pole was at the scene at Mincinglake on Tuesday and said the "thick smouldering embers" were alarming.
"It was just mostly the dry grass that was combusting and so there was just a lot of smouldering," she said.
'Exercise extra caution'
A hosepipe ban is in force across Devon and Cornwall due to the hot and dry weather putting pressure on water supplies. More than two-thirds of England are officially in drought.
Controlled burning is a planned process of setting fires to an area of moorland to remove old heather and vegetation and to minimise the risk of wildfires.
Cornwall's fire service said the ground and vegetation conditions remained "exceptionally dry" and would "significantly increasing the risk of fire spread".
It said: "Without an immediate and effective means of extinguishment, a bonfire or controlled burn can quickly escalate and become difficult to control, placing people, property, wildlife and the environment at risk.
"We also ask everyone to exercise extra caution when using barbecues, disposing of smoking materials and enjoying Cornwall's countryside, coastline and open spaces."
