Six people were killed and nine others injured after a massive three-alarm fire tore through a residential building in Sunset Park, Brooklyn, near Boro Park, early Thursday morning, November 5.

The blaze erupted shortly before 1:40 a.m. at 653 58th Street, rapidly spreading throughout the two-story building and sending flames shooting from multiple windows.

More than 230 firefighters and emergency personnel responded to the scene. Four victims were pronounced dead at the scene, while two others died after being transported to a hospital.

Among the nine injured were four civilians, three firefighters, and two police officers. Firefighters rescued four people from the burning building.

The fire also damaged a neighboring property and displaced several residents before being brought under control around 4:28 a.m.

Fire marshals are investigating the cause. Lithium-ion batteries were discovered at the scene, but officials have not determined whether they contributed to the blaze.
