A tragic fire in a Brooklyn apartment building resulted in one death and three injuries early Wednesday morning.

The fire broke out just before 4 a.m. on the second floor of the building, where two children managed to escape.

At least eight individuals were treated for injuries, with one sustaining life-threatening injuries and three others suffering minor injuries.

FDNY Commissioner Robert Tucker emphasized the dangers of unregulated lithium-ion batteries and thanked the public for heeding safety warnings.

FDNY Chief Fire Marshal Dan Flynn reported that the fire was ignited by a micromobility device, which blocked an exit when the battery failed.

There have been hundreds of lithium-ion battery fires in New York City this year, highlighting a growing concern.

Fire officials urged the public to call 911 immediately rather than attempting to extinguish lithium-ion battery fires themselves.

The cause of the fire is currently under investigation by the FDNY and other authorities.

The American Red Cross is providing assistance to families displaced by the fire.

The FDNY responded with a dozen units, including sixty firefighters and EMS personnel, to control the blaze.

Intense flames blocked the exit, trapping an elderly man inside, as reported by The New York Post.

Firefighters faced heavy smoke and flames, which hindered their initial attempts to enter the home to rescue the trapped individual.
