A 50-year-old woman and her 18-year-old daughter have been taken to hospital after a gas explosion at a house in Suffolk.
The blast happened at 0745 GMT in Chapel Road, Wrentham, near Southwold. It tore off the roof and destroyed the bedrooms.
The next door house was also badly damaged by fire and nearby properties were evacuated.
The woman and her daughter were taken to hospital with serious burns.
Police said the 50-year-old woman is in Broomfield Hospital in Chelmsford while her daughter is being treated at the Norfolk and Norwich Hospital.
Both are believed to be in a stable condition with injuries that are not thought to be life threatening.
Suffolk Fire and Rescue service said both houses were unsafe.
A district emergency planning officer and gas engineers are at the scene.
Neighbour Paul Scoggins said: "We were in bed and there was a massive explosion and the whole house shook.
"We heard some screams... we got our children out of the house."
John Wilcock, of Suffolk Fire and Rescue, confirmed the explosion had been caused by gas and said gas and electricity engineers were at the site.
He said the mother and her daughter had managed to walk out of the building.
"This is a tragic situation at any time but especially so on the 24th December," said Mr Wilcock.
"The firefighters have been in to the building, taken away any presents and stored them safely.
"So if there is anything we can do humanely like that, we will try and do it."
