The Flatbush building disaster in Brooklyn, New York, has claimed eight lives and left 17 people injured after a three-storey residential property collapsed beside an ongoing construction project, prompting a major search operation for possible survivors.
The building came down at approximately 4pm on Wednesday, trapping residents beneath bricks, timber and other debris. Four of the injured victims were critically hurt, while at least seven children were among those affected.
New York City Mayor Zohran Mamdani confirmed the latest casualties on Thursday, expressing sorrow over the loss of lives and extending his condolences to the victims’ families.
“Eight New Yorkers have now lost their lives and at least 17 have been injured, including three firefighters,” Mamdani wrote in a statement on X.
“There are no words for a loss of this magnitude. My heart is with the families and loved ones of those we have lost, those who are injured and everyone grieving today.”
He urged members of the public to stay away from the affected section of Flatbush Avenue, where approximately 250 emergency personnel were working to locate anyone still trapped.
Mamdani described the rescue environment as extremely dangerous, stressing the need for the public to keep clear of the site.

Firefighters intensify search for trapped residents
The New York City Fire Department (FDNY) continued its search operation into Thursday, deploying drones and specially trained canine units to locate possible survivors.
An excavator was also brought to the scene during the early hours to help remove heavy sections of the wreckage and create access for rescue workers.
Footage recorded on Wednesday evening showed firefighters carrying victims away on stretchers. One person was reportedly rescued at about 6.30pm after emergency workers dug through the debris.
A six-month-pregnant woman was also among those reportedly rescued. Her husband had spent hours searching for her after the building collapsed.
According to WABC, an ABC News affiliate, the man later confirmed that his wife had survived.
“I have an update. She is alive, she is still alive. I am very happy,” he said.
The rescue operation attracted dozens of onlookers, with some people breaking down in tears as emergency workers continued searching.
FDNY Commissioner Lillian Bonsignore warned that the operation would continue for an extended period.
“We know that we are not finished here, and we will likely not be finished for quite some time,” she told the crowd during an evening briefing.
Heavy rain poses additional challenge
Rescuers faced another potential obstacle as weather forecasts predicted heavy rainfall, thunderstorms and gusty winds across Brooklyn from Thursday afternoon.
The anticipated conditions raised concerns about the safety of emergency personnel working around unstable sections of the damaged property.
People displaced by the incident were provided temporary accommodation at the Bethesda Church of God in Christ, located opposite the collapsed building.
The residential property stood beside a construction site where a single-storey structure had previously been demolished. Excavation work was underway on the adjoining plot when the three-storey building fell into the construction pit.
A neighbouring property that shared a wall with the collapsed structure remained standing, although part of its wall was torn away, exposing rooms, a bedroom and wardrobes containing clothing.
Images from the scene showed the remains of apartments and staircases exposed to the street, illustrating the extensive damage caused by the collapse.
Authorities investigate possible construction safety breaches
New York City’s Department of Buildings has commenced an investigation to establish what caused the structure to collapse.
Attention has focused on the construction activities taking place immediately beside the residential property, particularly the excavation work and safety arrangements designed to protect neighbouring buildings.
Local television station NY1 reported that inspectors had identified several violations associated with the adjoining construction project during an inspection in May.
The reported breaches included continuing work despite an existing stop-work order, failing to provide adequate overhead protection for neighbouring properties and carrying out construction activities that did not conform to approved drawings.
The collapsed building also had a lengthy history of recorded violations. According to NY1, the city’s Department of Housing Preservation and Development had documented nearly 100 violations against the property dating back to 1972.
Property records described the structure as a three-storey building comprising four residential apartments and one commercial unit.
Investigators are expected to examine the building’s structural condition, the neighbouring excavation activities and previous regulatory complaints as they work to determine the cause of the disaster.
No official conclusion about what triggered the collapse has been announced.
The Flatbush building disaster has raised serious questions about construction supervision, regulatory enforcement and the protection of residents living close to active development projects.

Meanwhile, emergency workers continue removing debris as families await information about missing relatives and authorities work to establish the full circumstances surrounding the tragedy.
