Rescue teams have worked through torrential rain in search of victims ‌still buried in the rubble of a New York apartment building that collapsed, killing at least eight people.

Six people were found dead in ‌the wreckage and ‌two others died later ⁠from their injuries, city officials told reporters at the scene of the collapse. Two ​of those killed were children. The six adults killed included two construction workers.

Those injured in the collapse and its aftermath stood at 18, including four of the firefighters who led the rescue effort, officials said.

Mayor ‌Zohran Mamdani has ordered an investigation into dozens of linked construction sites.

A day after the collapse in the city’s Brooklyn borough, Mamdani ‌said the city would examine five companies associated with a construction site adjacent to the collapse and 100 more sites connected with those entities.

The construction site was undergoing excavation work that started earlier this year, historical satellite imagery showed. An official notice filed by a construction company in September informed authorities that the earthwork included “rock blasting,” official records showed.

Municipal building inspectors fanned out across the city to conduct inspections of the other sites “to ensure that if there is anything for New Yorkers to be worried about that we are ⁠on the scene and we are doing something about it”, the mayor ‌said at a ​press conference.

“If there is anyone or any entity operating in this city that bears responsibility for what happened, we will ​hold them fully ‌accountable,” Mamdani said.

The apartment building, which Mamdani said was home to several immigrant families, was built in 1930 and ​consisted of four residential units, according to official records. Two Ecuadoreans were among the dead.

The building’s collapse destroyed a wall of an adjacent residential block, exposing a staircase, closets and a bedroom.

Three ​other ​addresses were ordered vacated on the same side of ​the street as a precaution until safety inspections could be conducted, ‌officials said.

On Thursday, two excavators were seen clearing the debris under pouring rain. Mamdani said rescue work by some 250 personnel was continuing around the clock.

“We will be here until we are 100 per cent sure there are no more people trapped,” Fire Department Commissioner Lillian Bonsignore told reporters.

“We always assume that there are more people there until we can access ​the ground. So until we remove some of the bigger debris and are able to search beneath them, this ​will remain a rescue operation.
