Two people were killed and at least 17 others injured when a building collapsed Wednesday afternoon in the Flatbush neighborhood of Brooklyn, New York City, sparking an extensive emergency response and search operation.

The incident occurred at approximately 4 p.m. near the intersection of Bedford and Flatbush avenues, directly adjacent to a construction site. According to the Fire Department of New York, the collapsed structure appeared to be three stories high with a ground-floor business, standing beside an excavation pit where a previous building had been demolished.

First responders pulled multiple individuals from the wreckage. Officials confirmed Wednesday night that two people died from their injuries, while four others were hospitalized in critical condition. The injured total of at least 17 included seven children and one firefighter. Authorities cautioned that the casualty count could rise as search and rescue operations continued, because it remained uncertain exactly how many people were inside the building at the time of the collapse.

Firefighters utilizing dogs, drones, and hand-digging techniques combed through piles of bricks and wood that filled the construction pit. The collapse also stripped away the shared wall of an adjoining building, leaving interior rooms exposed. City officials, emergency personnel, and building inspectors remained at the scene into the evening to conduct recovery efforts, ensure structural stability, and investigate the cause of the disaster.
