Several houses are on fire in Pittsburgh's Lawrenceville, Pennsylvania, with heavy wind causing difficulties in controlling the flames and firefighters urging all to stay away from a "very active scene".
The fire is estimated by the Pittsburg firefighters to be three-structure and a 3-alarm.
One house on Wickliff Street that caught fire collapsed from the top. McCandless Ave is closed between Duncan Street and Stanton Avenue.
Earlier, Allegheny County officials said that several roads had been closed in the area.
No injures or fatalities have been reported, and the reason for the fire is not yet known.
