Homes have been evacuated and rail services were disrupted after firefighters found a gas cylinder in a blazing shed in West Yorkshire.
Fire crews were called to the shed, near Railway Cottages, South Elmsall, near Pontefract, at 0445 BST.
A 100-yard (91m) cordon remains and the row of cottages has been evacuated until the cylinder, which is potentially explosive, can be cooled.
