Nottinghamshire house 'exploded in front of us'
An explosion has injured four people at a house in Nottinghamshire.
The county's fire service said the home in Wright Street, Newark, was severely damaged in the blast, thought to be caused by gas, at 17:10 BST.
Four people were taken to hospital, police said, but no more details have been released.
Firefighters are searching the building for other victims. About 100 neighbours have been moved out of their homes.
Eyewitness Cormac Fleming was taking his dog for a walk with his children when he saw the building "explode".
He described to the BBC's Geeta Pendse how he helped rescue people from the house.
