A house collapse has sparked a mass evacuation on a street in Portsmouth with fire crews searching through rubble to check for anyone trapped in the wreckage.
Emergency services raced to Langford Road in the Copnor area of the city in the early hours of this morning.
Two people have been taken to hospital, the fire and rescue service said, although the extent of their injuries is currently unconfirmed.
A number of crews from Hampshire and Isle of Wight fire and rescue were sent to the scene, including specialist USAR (Urban Search and Rescue).
Officers from Hampshire Police have closed the road in both directions and a number of other properties have been evacuated.
South Gas networks and UK Power were also called to the scene to isolate power and services to prevent further damage.
The cause of the collapse is not yet known.
USAR Teams from Hampshire Fire and Rescue carried out search and structural checks on neighbouring properties.
Parts of the roof have given way and come crashing down causing a massive smoke cloud nearby vehicles have been covered in dust.
An investigation is currently underway to find out what caused the house to collapse.
A spokesperson for Hampshire Fire confirmed crews left the scene shortly after 11am, saying: "Firefighters were called at 08:30 to Langford Road in Portsmouth after a terraced house collapsed this morning.
"One crew from Southsea Fire Station and a USAR advisor were in attendance to assess the damage and make the scene safe. Two casualties were treated by South Central Ambulance Service paramedics before they were taken onto hospital.
"A number of houses were evacuated and the road was closed as a cordon was put in place.
"The incident was handed over to Hampshire Constabulary and Portsmouth City Council engineers as utility companies worked to isolate the power and gas supply."
Police meanwhile said they were working with the council to ensure all nearby houses were evacuated, with the council drafting in structural engineers to inspect the scene.
A force spokesman said: "We are assisting Portsmouth City Council with the road closure so they can evacuate nearby houses and, for any further enquiries, please direct to the council."
