Four city firefighters were hurt while responding to a fire in the Bedford-Stuyvesant section of Brooklyn early Monday morning.
Dramatic video captured the moment part of 667 Jefferson Avenue came crashing down on firefighters.
They were brought to Kings County Hospital with minor injuries.
No civilian injuries were reported.
The fire department says clutter in the building is making it difficult to extinguish the flames.
The cause of the fire is under investigation.
