Heavy black smoke can be seen for kilometres after a massive fire engulfed an industrial site in New York.
Firefighters struggled to contain the blaze, which broke out at the former Bethlehem Steel site early on Wednesday morning (local time).
It's thought the fire was sparked when a hot bulb fell on some debris.
Hundreds of firefighters were called to battle the blaze and Commisioner Garnell Whitfield told local media the fire could burn for days.
One firefighter broke an ankle, however that is the only injury which has been reported thus far.
The six-block-long site is home to several businesses, located in Lackawanna, just south of Buffalo.
Nearby residents were asked to shelter in place to avoid the thick smoke.
Investigators have yet to enter the building.
