Part of a highrise apartment in New York City collapsed Wednesday morning, leaving a corner of the public housing building a pile of rubble.
The New York City Fire Department (FDNY) said it had no immediate reports of injuries. It said it was responding to a report of a gas explosion that collapsed an incinerator shaft in the 20-storey building in the Bronx. Authorities said no residential units were affected.
"An investigation is underway to determine the cause of this event and the extent of any damage beyond the reported exterior damage to the chimney," the city's housing authority said in a statement.
Video from the scene shows a highrise building, with one corner collapsed from the ground floor to the roof. Videos from nearby residents showed a cloud of dust billowing over the block moments after the collapse, which happened around 8:10 a.m. ET.

The rubble pile was littered with air conditioners, which appear to have been ripped out of apartment windows by the falling bricks.
New York Mayor Eric Adams said he was briefed about the emergency and officials were still getting a full assessment. "Please avoid the area for your safety," he wrote on X.
