PITTSBURGH (WPXI)— Crews were called out to a home near the intersection of Bandera Street and Ater Way just after 7 p.m. Saturday for a 3-alarm fire. Firefighters worked for multiple hours trying to extinguish the flames. As they doused the three-story home from above, flames persisted, pouring out of the roof. Several streets nearby were blocked by fire trucks, and many people just stood by watching crews get to work. Fire officials believe no one was present in one of the homes. Pittsburgh Public Safety says a firefighter had to be checked out by a medic on scene for breathing issues and another had to be taken to the hospital. There’s no word yet on what sparked the flames or how much damage was done.
