Six people were killed and several others were injured after a major fire tore through a two-story residential building in Brooklyn’s Sunset Park neighborhood early Thursday morning.
The blaze was reported at about 1:40 a.m. on 58th Street between 6th and 7th avenues, prompting a large emergency response involving more than 200 firefighters and medical personnel.
Four adults were pronounced dead at the scene, while a man and a woman were taken to a hospital and later pronounced dead.
Authorities said the cause of the fire remained under investigation.
Firefighters arriving at the property found flames engulfing parts of the building, with fire visible through second-floor windows as crews worked to contain the blaze.
The fire spread through the structure and, according to one account, extended to a neighboring home before being brought under control.
Firefighters continued working at the scene afterward, searching walls and siding for remaining pockets of fire.
Reports differed slightly on the number and severity of injuries, but authorities said civilians and firefighters were among those hurt.
The FDNY said six civilians were injured, including two critically, while other reports said four civilians suffered non-life-threatening injuries and another victim was in critical condition.
Three firefighters were also injured, with their injuries described as minor or non-life-threatening.
The fire caused extensive damage to the residence and displaced multiple people.
The American Red Cross was assisting residents left without housing, while city officials said displaced New Yorkers were being connected with temporary accommodation and other support.
Hazardous-materials personnel were called to the scene after lithium-ion batteries were discovered inside the property.
Reports said either one or two batteries were found, but officials had not determined whether they were connected to the fire.
Investigators were continuing to examine the cause of the blaze.
New York City Mayor Zohran Mamdani expressed condolences to the victims’ families and praised the response by firefighters and other emergency personnel.
He also said the city was examining fire-safety concerns involving lithium-ion batteries while stressing that the cause of Thursday’s fire had not yet been established.
No names or ages of the six people killed had been released in the immediate aftermath of the fire, although officials said all of those who died were adults.
