JERSEY CITY - Several Jersey City families are attempting to sort through their belongings following a large fire.

The blaze damaged several buildings on Fairmount and Monticello avenues. Investigators say the fire may have been caused by a faulty dryer at a Laundromat.

Authorities say no one was seriously injured but the fire destroyed several businesses and left at least six families homeless. Nine firefighters were injured while battling the blaze.

Officials say a firefighter was on a roof overhanging a ground floor business when he was knocked to the ground by roofing material he and other firefighters were removing.

The firefighter was taken to a hospital for treatment. Eight other firefighters were also taken to a hospital to be treated for heat exhaustion.
