JERSEY CITY, N.J. (PIX11) — Four firefighters were hurt battling a four-alarm fire in Downtown Jersey City Tuesday afternoon, according to officials.

Officials said the fire appeared to have started in the back of a building at 234 Montgomery St., a building that’s vacant and under construction, and extended to 236 Montgomery St. JCFD said they are working with Red Cross to relocate four adults and one child from that building.

Four firefighters suffered non-life-threatening injuries due to collapsed stairs, according to the Jersey City Fire Department. They were taken to the hospital to be treated. There are no civilians injured, JCFD said. However, the building was evacuated while officials wait for PSE&G to cut the building’s power.

JCFD advises drivers to avoid Montgomery Street from Jersey Avenue to Grove Street.

The cause of the fire is still under investigation.
