Firefighters on Thursday recovered four more bodies from the rubble of a building in Brooklyn that collapsed, bringing the death toll to eight. 

The three-story building located at the edge of a construction site collapsed Wednesday afternoon, the Associated Press reported. 

Firefighters and police continued to dig through the rubble on Thursday, using dogs to help locate survivors. In addition to the eight deaths, 17 people have been hospitalized with injuries, including four who are in critical condition. 

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

The cause of the collapse is under investigation. New York City’s buildings commissioner, Ahmed Tigani, pointed out that construction workers were excavating an empty lot next door for a new building when the building fell.
