At least 17 dead, including 9 children, in massive fire at NYC apartment; 63 injured in total

NEW YORK -- At least 17 people are dead, including nine children, following a massive fire in New York City on Sunday, officials said.

About 200 firefighters were battling the five-alarm blaze at the 19-story high-rise in the Bronx borough's Tremont neighborhood.

FDNY Commissioner Daniel A. Nigro said a malfunctioning electric space heater caused the fire. Smoke alarms in the building were operable.

At least 63 people were injured, with 32 sustaining "life-threatening" injuries and 13 "clinging to their lives" in nearby hospitals, according to the New York City Fire Department.

Neighbors recorded video of massive smoke plumes and FDNY rescues during the deadly Jan. 9 apartment fire in the Bronx, New York City.

Mayor Eric Adams already said the tragedy "is going to be one of the worst fires we have witnessed here in modern times in the city of New York."

For context, a total of 73 people died in New York City fires in all of 2021.

Officials said the fire appears to have originated in a duplex apartment on the building's third floor. Many of the injuries were found on the upper floors, and officials believe smoke inhalation may be to blame.

FDNY Commissioner Daniel Nigro details the effort to rescue people from a burning building in the Bronx.

Firefighters arrived on the scene within three minutes of the initial 911 call and were met with fire in the hallways, Nigro said. A door that was left open allowed the fire and smoke to spread, Nigro added, describing the fire as "unprecedented."

The fire engulfed two floors of the building but smoke trailed through all 19 floors, he said.

"The smoke conditions in this building are unprecedented," he said.

Dramatic pictures posted to social media show fire gushing out of multiple windows in the building. FDNY began receiving calls from multiple residents on upper floors just before 11 a.m.

Residents described the events that unfolded as "traumatizing" as they escaped from the building during the fire.

Josh Einiger, a reporter with our sister station WABC spoke with the man who lived in the apartment where the fire started.

"We was sleeping and then my kids were screaming saying fire, fire," Mamadou Wague said.

An FDNY firefighter was caught on camera rescuing a baby from a deadly Bronx apartment fire that killed more than a dozen. "New York City Fire Department don't play," said Tanisha Ashe as she recorded the video.

The fire started in Wague's third-floor duplex, where he lives with his wife and eight kids, one of whom was trapped on a burning bed.

Wague has burns on his nose from when he leapt through the flames to rescue his daughter, who is burned but alive.

"I don't want anybody life -- I don't want to hear anybody dead in this fire, that's what I worry about," Wague said.

The fire has since been put out.

Additional details, including the conditions of the other victims, were not immediately available.

This was the second major fire in the Bronx over the weekend. A four-alarm fire in the Fordham Heights section of the Bronx that began early Saturday morning injured a firefighter and displaced three families, WABC reported. A lithium-ion battery sparked the fire, officials said.

Last week, a fire that broke out on the second story of a row house in Philadelphia killed 13 people, including seven children.
