Firefighters believe that a forest fire could have been started by a discarded cigarette. 

Crews were called to the blaze in Santon Downham Woods in Thetford Forest, on the Norfolk-Suffolk border, at about 1.30pm on Saturday. 

Photographs and videos posted on social media showed the fire spreading quickly through the woodlands. 

A spokesman for Brandon Fire Station said on arrival crews found a large area of the forest well alight. 

Crews used a hose reel and beaters to get the blaze under control. 

On social media, Brandon Fire Station said the fire is believed to have started by a discarded cigarette.
