Four people were taken to hospital suffering from the effects of breathing in smoke after a major fire destroyed a house in Hampshire.
About 40 firefighters were called to the two-storey mid-terrace property at Curlew Gardens in the Wecock Farm area of Waterlooville just after midnight.
The whole house was destroyed. Its structural safety is being assessed before an investigation gets under way.
Residents were evacuated from adjoining homes helped by Red Cross volunteers.
The adjoining homes were damaged by smoke.
Both the fire service and Hampshire Police are investigating.
The fire service said the house would need to be "shored up" in places to be made safe before investigations could begin.
Station manager Paul Coates said: "On arrival, the initial crews were faced with a very serious fire and flames coming out of the roof of the third house along a row of seven terraced properties.
"They did a sterling job in tackling the fire and stopping it from spreading to the adjoining properties and firefighters were also dispatched to work on the neighbouring buildings where the roof spaces were starting to smoke.
"This would have no doubt been a much more serious incident had it not been for everyone's hard work."
