Firefighters received a call at 12:23 a.m. about the blaze at a single-family home in Midwood, a leafy section of Brooklyn known for its low crime and large Orthodox Jewish population. Long said more than 100 firefighters responded and brought the blaze under control at around 1:30 a.m.
There was no immediate word on the cause of the fire. Long said it was being investigated by the city fire marshal’s office.
Fire officials had no other immediate details, but the New York Post reported the blaze occurred in a brick home.
The newspaper said that as firefighters worked to put out the fire, paramedics struggled to help the victims.
Neighbor Nate Weber told the paper that he saw children being wheeled away on stretchers.
“I just turned away. I didn’t even want to look,” he said.
Weber told the New York Daily News he heard the children’s mother yelling for someone to rescue her children after she jumped from a window.
“I heard a woman yelling: ‘My kids are in there. Get them out! Get them out!'” he told the Post.
