Two house fires caused damage in Arlington over the weekend.

A fire in the attic of a home on the 900 block of Patrick Henry Drive, in the Dominion Hills neighborhood near Seven Corners, caused significant damage late Saturday night. Two residents were displaced by the fire and the Red Cross responded to the scene to assist them, according to Arlington County Fire Department spokesman Capt. Gregg Karl.

Another house fire was reported around the same time on the 2500 block of Walter Reed Drive, at the Windgate townhouse community. The fire was on the first floor of the home and was quickly extinguished.

Both fires are under investigation, Karl said.
