A New York City building collapse shook the Bronx on Wednesday morning when part of a 20-storey high-rise known as the Mitchel Houses gave way after a gas explosion.
Emergency services rushed to the scene, but officials later confirmed that no one was injured .
According to reports, the incident happened at around 08:10 EST (14:10 SAST) at 205 Alexander Avenue, near East 135th Street.
A section of the building’s incinerator shaft collapsed, scattering rubble across the street.
Police and fire officials immediately evacuated about 40 nearby apartments to make sure residents were safe. K9 search dogs were deployed to comb through a 10-foot-high pile of debris, confirming that no one was trapped .
Authorities explained that a gas explosion triggered the collapse. In simple terms, a gas explosion happens when leaking gas builds up in an enclosed space and ignites, often due to a spark or flame.
The force of the blast can damage walls, floors, or entire sections of buildings. Following the blast, gas services in the area were shut off as a precaution, and officials also reported a collapsed underground water main.
The New York City Department of Buildings is now examining the structure to check for faults and assess whether it is safe for residents to return. The Housing Authority is also running its own investigation.
So far, damage has been reported mainly to the exterior chimney and incinerator shaft of the affected tower .
Mayor Eric Adams posted on X (formerly Twitter) that he had been briefed on the situation.
“We are getting a full assessment from first responders. Please avoid the area for your safety,” he wrote.
Authorities have asked drivers to stay clear of Alexander Avenue and surrounding streets, warning of traffic disruptions as emergency work continues .
Residents captured and shared videos online showing part of the building ripping open, with dust and debris scattering onto the road. Emergency crews are continuing their work on site, while displaced tenants are being assisted by city housing officials.
