Pittsburgh Firefighters responded to house fire on the 8000 block of Susquehanna Street in Wilkinsburg around 10:15 p.m.
When crews arrived, they found the second and third floors of the three-story home fully involved. The fire went to two alarms shortly before 11 p.m.

The home was abandoned so no residents were displaced.
One firefighter was treated for a minor hand injury.
Firefighters prevented any damage to neighboring structures, including a home next door that is separated by a few feet.
The Allegheny County Fire Marshall responded on scene. Wilkinsburg Police, Eastern Area Prehospital Services and the Salvation Army also responded.
