(AP) HARRISON, N.J. - Firefighters are battling a five-alarm fire at a northern New Jersey industrial building that has extended to some adjoining buildings.
At least two firefighters have sustained injuries while battling the blaze, which broke out Sunday morning in Harrison. Their injuries are not believed to be serious.
It’s not yet clear what sparked the blaze, which apparently started on the ground floor and spread toward a nearby apartment building. No civilian injuries have been reported.
The fire sent heavy, black smoke spewing from the two-story building in the Hudson County community. Witnesses also reported hearing an explosion shortly after firefighters arrived.
Traffic is being detoured in the area, leading to some travel delays. The fire also forced organizers to re-route a St. Patrick’s Day parade being staged in the area.
