The FDNY confirmed Thursday morning that a fifth person died in the Flatbush building collapse that left more than a dozen people injured.

Officials say 250 fire and EMS personnel responded to the collapse of a three-story building at 1321 Bedford Ave. just after 4 p.m. Wednesday.

The structure crumbled into an adjacent construction and excavation site at 2625 Bedford Ave. Fire officials say a major technical rescue response followed.

A total of 23 patients were hospitalized, according to the FDNY. Five were dead upon arrival.

Four were listed in critical condition, while five others sustained serious but non-life-threatening injuries. Ten people with minor injuries were also taken to local hospitals.

As of this morning, Flatbush Avenue remains closed from Farragut to Clarendoon roads. Multiple side streets are also closed off, including Newkirk and Foster avenues.

Multiple New York City officials and agencies have been posting social media updates following the collapse.

The American Red Cross and the New York City Emergency Management Team is offering resources to those impacted. This includes food, clothing and health services.

Anyone who has not had the opportunity to register for assistance should call 877-REDCROSS.
