A fast-moving fire tore through a building in East Williamsburg late Sunday night, injuring three firefighters and causing part of the structure to collapse, according to the FDNY. It happened just before 10 p.m. on Grand Street, between Catherine Street and Morgan Avenue. Officials say the fire started on the first floor of a three-story building. There’s a business on the ground level and apartments on the floors above. The flames spread quickly and extended into the building next door. At one point, crews had to back out and fight the fire from outside because the building was no longer stable. Part of a wall from the main building collapsed into the street. Another section fell in the back, raising concerns about nearby buildings.

Despite the dangerous conditions, everyone inside made it out safely. Three firefighters were taken to the hospital — one with moderate injuries and two with minor injuries. They are all expected to be OK. More than 200 emergency responders were on the scene as crews worked for hours to get the fire under control. It was finally brought under control early Monday morning. Fire marshals are now investigating what caused the fire.
