The Fire Department of New York is on the scene of a fire at a large residential building in Upper Manhattan Wednesday morning after eyewitnesses reportedly heard an explosion at around 9:31 a.m. EST.
Firefighters were still fighting the blaze at 1646 Park Avenue in Harlem around an hour later, and eyewitnesses told Fox News that debris from the partial collapse had spread several blocks throughout the neighborhood.
Around that same time, the FDNY upgraded the incident to a four-alarm blaze and confirmed that it was being categorized as a “multiple dwelling explosion and collapse” being handled by upwards of 168 firefighters. On Twitter, one eyewitness said he was on his way to work when he came across the scene and saw nearby cars covered by bricks and glass.
It has yet to be confirmed whether or not any occupants remained inside the property, but a local hospital was reportedly treating at least 11 victims at a nearby emergency room.
