Officials are on the scene of a gas explosion at a building in Mott Haven.

According to the FDNY, the incident happened at Alexander Avenue and East 137th Street and East 135th Street.

Officials say an incinerator shaft collapsed from the multi-dwelling. Incinerator shafts in New York City buildings were once used to dispose of trash, which was then burned on site. But they have largely been replaced with trash compactors, which can use the same chutes, according to the Associated Press.

According to the FDNY, there are no reported injuries as of right now.

News 12 has seen two canines search the rubble to make sure no one is under it.

Neighbors tell News 12 Brittany Cadet where the building collapsed is where the pipes go through the building. They say the boiler and where the pipes run into is what exploded and caused the area around it to crumble.

Some residents that spoke with News 12 say they had been smelling gas for some time in the building.

"Today is very strong," said one resident. "I feel so scared. I don't want to live there anymore, because we have a lot of complaints. But they don't pay mind."

"I was in my house. When that happened, we feel like the building was moving around. We thought it was an earthquake. So I was so scared," said a building resident to News 12.

Building residents are concerned about their belongings inside the building.

"My wheelchair is upstairs, my medical supplies, and I really need them bad. My apartment is open. We don't care about none of the belongings, but my medical supplies and my wheelchair," said one resident.

"I just heard BOOM. For a minute after the boom, we saw the birds flying, we started looking around, we saw a little smoke. And then after the little smoke the building started [crumbling]," said Edward, one resident who was dropping off his daughter at school.

Mayor Eric Adams has been briefed about the situation in Mott Haven.

New York City mayoral candidate Zohran Mamdani has also been briefed on the situation.

"I’m grateful for the FDNY and other first responders who rushed to the scene of a partial building collapse in the Bronx this morning. No injuries have been reported — praying it stays that way."

According to News 12’s research, the building had a partial stop work order in effect.

Before the collapse, they had a total of 19 violations, seven of which were active.

That partial stop work order was due to inactive licenses for an active project, although we cannot confirm what that project was.
