Family escape explosion in house in Gower
Firefighters say a family are lucky to be alive after an explosion at a house.
Mid and West Wales Fire and Rescue Service were called to the semi-detached property in the village of Llangennith, Gower, at 0200 GMT.
Five people escaped, with one man suffering slight injuries after the blast, which is thought to have been caused by gas.
Three people were also evacuated from neighbouring properties and all eight spent the night in a nearby pub.
Rob Martin of the fire service, said the family were "extremely lucky to get out".
Mr Martin, a station manager, said: "They were extremely lucky that the explosion wasn't any worse.
"The property was very badly damaged and it's not, in fact, safe to enter.
"We haven't sent any firefighters in to do anything and they're extremely lucky to get out. If the explosion had been any larger it would probably have demolished the house.
"Because it's so dangerous I'm probably not going to enter the house so I am trying to conduct the investigation as best as I can externally and through doing interviews with the various witnesses.
Mr Martin said firefighters were still not able to enter the property early on Saturday because it was so dangerous.
"It seems like there was a gas fault there. Again it's very difficult to determine what occurred because we can't actually get into the property, it's not safe to do so," he said.
The five people who escaped the explosion are staying in a local pub called the King's Head, with three people from adjoining houses which were evacuated during the night.
It is likely that at least one of the houses will have to be demolished.
Structural engineers and gas experts from Transco have been at the scene and an investigation will be carried out by fire officers into the cause.
