Two people are missing after a suspected gas explosion caused a village bungalow to partially collapse.
Emergency services were called around midday to Lidgate, near Newmarket, and firefighters were faced with a series of explosions from the back of the property.
Two people are still unaccounted for, according to Suffolk Fire and Rescue Service, who sent four crews to the scene.
Neighbours described hearing a loud bang, with one likening the sound to a "First World War bomb".
Darren Reeve, Suffolk Fire and Rescue station commander, said investigations into whether anyone was inside the property are still ongoing.
"Crews were called approximately midday to a house fire. Three fire engines responded to this and they were faced with multiple explosions from the rear of the property," he said.
"It's quite a big bungalow and the rear of the bungalow is totally destroyed by fire.
"It was a very large explosion at the time followed by multiple smaller ones. However, we are still investigating how that occurred.
"There is extensive structural damage which has slowed down firefighting activities due to the integrity of the building.
"So we currently have two persons unaccounted for at the moment are working extremely hard with police and ambulance to investigate.
"We'd like to thank the neighbours, on our initial attendance we worked quite hard with the neighbours to try to ascertain whether anyone was in the property.
"We were then given information about the residents who live here and at this moment, that's all the information we have."
Mr Reeve added that the fire service would continue to work with police and the HART (Hazard Area Response Team) to resolve the incident as soon as possible.
A neighbour, who did not want to be named, said: "My daughter heard a bang and about 20 minutes later, I saw smoke billowing out. Our immediate neighbour said it was pretty loud. I think there were two explosions."
