New York City's socialist Mayor Zohran Mamdani vowed Thursday to conduct probes on 100 construction sites after a deadly building collapse in Brooklyn earlier this week.

A total of eight people died in the collapse of a three-story building located at the edge of a construction site on Wednesday. Another 18 people have been injured in the incident. Two of the deceased were children and another four were firefighters, according to Bloomberg. 

Mamdani said in a press briefing that the city has identified five entities associated with the neighboring construction site, which were associated with 100 other sites across New York City. A sweep of those sites will be conducted later Thursday.

“A tragedy of this magnitude demands a comprehensive and thorough investigation that includes both the construction site and the building which collapsed,” Mamdani said, adding that the probe "will extend to any and all sites that those who operated these sites are currently operating.”

It is not clear how many people are still missing, according to officials, but New York City’s buildings commissioner, Ahmed Tigani, said construction workers were excavating an empty lot next door for a new building when the building fell.  

“These were our friends and our neighbors, parents and children,” Mamdani said. “Let us continue to hold close those who have been plunged into unimaginable grief.”

The building is a mixed-use structure with apartments situated over ground-floor commercial space.
