UPDATED, 10:12 P.M.: Portsmouth firefighters knocked down a five-alarm fire that raged for more than three hours on the top of the roof of the Bow Street condominiums at One Harbour Place.

Emergency communications reported the fire was officially knocked down just after 10 p.m. and that crews were in the process of mopping it up. UPDATE, 9:54 P.M.: Firefighters from several Seacoast area communities continued to battle a five-alarm fire at One Harbour Place as more flames shot up into the cold night sky.

Fire Chief Christopher LeClaire said the fire that began in the chimney on the east end of the luxury condominium complex spread to a few condo units. As firefighters vented the roof, the bright red and orange flames continued to burn. Smoke also continued to fill most of the lower end of downtown Portsmouth thanks to the wind. Fire engines, fire rescue ambulance and fire apparatus from Seacoast area communities such as Durham, York, Maine, Exeter and Hampton continued to arrive to join firefighters from Portsmouth, Dover, New Castle, Rye, Greenland, Newington and Kittery, Maine.

He said there are two companies of firefighters still battling the blaze on the roof. They still have fire inside the top level condominium units.

LeClaire said he believes it's going to take quite a while to totally get the fire under control.

UPDATE, 8:40 P.M.: Firefighters are still battling flames on the roof of the building. They continue to vent the roof, and each time they take out another chunk of the roof, more flames shoot into the air. One Portsmouth resident who lives in the South End said he could see the flames licking the top of the building from State Street and that there is "smoke all over the downtown."
