Firefighters are tackling a huge blaze at a building in Leeds used for storing chemicals that lit up the sky and sent plumes of thick black smoke across the city.
Witnesses reported hearing loud bangs as the inferno engulfed the Tradepak industrial site in the early hours.
Fifteen fire engines and two aerial appliances are at the scene of the blaze in Albion Way, which has spread to a neighbouring building.
Emergency services initially warned there was a risk of toxic smoke due to to "potentially hazardous chemicals" on the site.
But they later said that residents in the city centre should keep windows and doors closed "as a precaution" until smoke from the fire clears
West Yorkshire Police said: "Emergency services are currently attending a large-scale fire at Albion Way in Leeds.
"Police were called at about 2.34am this morning to respond to the incident, which is taking place at a business on the site. A number of fire engines are currently attending."
The Armley Gyratory Road had been closed due to the large amounts of smoke from the fire, but has now re-opened.
Other roads around the site on the industrial estate remain shut
