Fire crews battled a huge blaze on grassland in north London.
Around 60 firefighters tackled a fire the size of three football pitches at Tottenham Marshes.
Flames spread over three hectares of scrubland in Lee Valley Park near Marigold Road just after 8pm this evening.
Dramatic images show fire crews battling huge, orange flames.
Witnesses described seeing fire "as far as the eye could see".
A London Fire Brigade spokesman said: “Crews are working hard to bring this fire, which is covering an area the size of around three football pitches, under control.
"Grass fires cause a great deal of damage to open spaces, property and wildlife but the public can help us stop them from starting by making sure that their cigarettes and barbecues are extinguished properly, and that glass bottles, which can concentrate the sun’s rays onto dry grass, are disposed of carefully.
"It's also important that if you do notice a fire on open grassland or in woodland that you don't attempt to put it out yourself as grass fires can travel very quickly and change direction without warning."
The fire comes after six fire engines rushed to a grass fire in Woodford Green around 2.30pm this afternoon as temperatures in the capital soared above 25 degrees.
Two hectares of grass and scrubland was alight off Meadgate Avenue.
Some 35 firefighters from Woodford, Hainault, Ilford, Leytonstone and Walthamstow fire stations were at the scene.
The cause of the fire is currently unknown.
