A mother and her two daughters were killed in a fire that tore through a Bedford-Stuyvesant apartment building early Friday morning, authorities said.

The blaze broke out on the third floor of a four-story building on Gates Avenue, between Throop and Tompkins avenues, around 5 a.m., the FDNY said.

Firefighters arrived at the scene within three minutes after receiving an emergency call and encountered heavy fire and smoke, FDNY Battalion Chief John Sarrocco said at a news conference in Brooklyn. 

At the rear of the apartment building, they pulled the mother and children from a bedroom and began performing advanced life support on them outside the residence, he said.

The three victims, identified by police as Danielle Havens, 48, Journee Miles, 11, and Keslee Miles, 9, were rushed to NYC Health + Hospitals/Woodhull, where they were pronounced dead, Sarrocco said.

Fire marshals deemed the blaze an accidental fire sparked by "cooking carelessness," the FDNY said. There was no smoke alarm inside the apartment when the fire broke out, the department said. 

All of the building's other residents were able to escape without injury, fire officials said.

FDNY Commissioner Laura Kavanagh said the blaze was contained to the third floor of the building. The fire department declared the blaze under control just before 6 a.m.

“This is an incredible tragedy for this neighborhood and for this family,” Kavanagh said. “We will be here all morning working with the Red Cross, working with OEM and working with the city to support the family.”

Mayor Eric Adams, who owns a home near the scene of the fire in Bedford-Stuyvesant, toured the site of the blaze late Friday morning.

“Our hearts go out to the family, the neighbors, the block. You know, this is a block from my residence,” Adams said. “There’s some learning experiences here that we’re going to incorporate based on what we saw inside, but it’s just really an unfortunate situation, and our heart goes out to the family.”
