The Pittsburgh Bureau of Fire was first called to a one-alarm fire residential fire in the 1200 block of Lincoln Avenue just before 1:15 p.m.

The fire began in the basement area of the residence and spread upstairs, displacing four people who were treated on scene by EMS for smoke inhalation. The Red Cross is helping to provide the residents with temporary accommodations.

After the Lincoln Avenue fire was extinguished, the same group of firefighters was immediately called to a second one-alarm residential fire in the 1500 block of Oberlin Street in Lemington-Belmar. The fire began in the attic area. The occupant was not at home at the time of the fire.

A firefighter from Engine 17 suffered a knee injury working the Oberlin fire and was transported for medical attention. 

The Fire Investigation Unit is investigating the exact cause of both fires.
