JERSEY CITY — Seven firefighters were hospitalized and over two dozen people were displaced by a three-alarm fire on Sunday, according to reports.

News 12 New Jersey reported that the fire broke out in Jersey City on the 600 block of Bergen Avenue at the intersection with Fairview Avenue. Someone reportedly ran to a nearby firehouse to alert firefighters to the blaze.

In a video posted to social media, smoke and flames can be seen billowing above the roof of one three-story mixed-use building. Another video on youtube shows fire crews on the roof of the building and going into a deli next door that was also damaged.

Fire Chief Steven McGill told News 12 New Jersey that seven firefighters went to the hospital. However, none of their injuries are considered life-threatening.
