ALEXANDRIA, Va. (WDVM) — One person was injured and around 17 were displaced due to a Sunday apartment fire on the 2600 block of Arlington Drive in Alexandria. On Tuesday, the cause of the fire was determined to be “improperly discarded smoking materials.”

Fire crews were called to the three-story, garden apartment around 8 a.m. on Sunday. The fire was visibly engulfing a third-floor balcony when firefighters arrived on-scene.
