Firefighters were battling Tuesday night to get a four-alarm fire under control in the Greenpoint section of Brooklyn.
The New York City Fire Department said that that the fire started around 7 p.m. Tuesday evening in a recycling plant on Humboldt Street.
Firefighters said that the front part of the building collapsed, preventing them from entering, which they said made the operation even more difficult.
"It's become unstable. We can't get in close enough to quickly put it out," said Deputy Assistant Chief Jack Mooney of the FDNY. "It becomes a long operation with a lot of water and a lot of large-caliber streams."
No one was injured, and none of the surrounding buildings were damaged.
