At least two people were killed and more than 10 others injured after a three-storey apartment building collapsed in Brooklyn on Wednesday, New York City officials said.

Rescue teams continued searching the rubble for possible survivors and additional victims.

The four-unit apartment building, constructed in 1930, collapsed into an adjoining construction site in the Flatbush area. Excavation work was underway at the site when the incident occurred.

The cause of the collapse remains under investigation, said John Esposito, chief of the New York City Fire Department.

The building collapsed at around 4pm local time on Wednesday. The number of residents inside the building at the time was not immediately known. Officials also had not confirmed how many construction workers were present.

Two Killed, More Than 10 Injured

Mayor Zohran Mamdani confirmed that at least two people had died. More than 10 others were taken to local hospitals with critical and non-life-threatening injuries.

Fire Department Commissioner Lillian Bonsignore said officials had identified 19 victims, including seven children.

She did not disclose whether the two fatalities involved children or adults. A firefighter also sustained minor injuries.

A firefighting crew already in the neighbourhood reached the scene within a minute of the collapse. The crew helped rescue the first victims from the debris, authorities said.

Rescue Teams Search for Trapped Victims

Rescue workers used search dogs and manually removed debris while looking for people trapped beneath the rubble.

Local television footage showed emergency crews clearing debris in buckets and searching spaces beneath the collapsed structure.

New York television station WABC-TV reported that rescuers pulled at least four survivors from the wreckage around two to two-and-a-half hours after the collapse. A pregnant woman was among those rescued.

Esposito said the search could take several days as teams worked to examine the entire site.

“We do not know how many people are missing overall,” he said.

The fire department initially reported four critically injured people and six others with minor injuries. Officials later provided updated figures as rescue operations continued.

Authorities said the investigation into the building collapse was ongoing.
