Original post: 

Pittsburgh Bureau of Fire responded to the 1100 block of East Carson Street around 6:15 p.m. for a 2-alarm structure fire in a commercial building with residences upstairs.

When firefighters arrived on scene they found a fully involved fire on the upper floors, mainly at the back of the building, with reports of possible entrapment.

Firefighters searched the building and found no one was left inside. Thirteen displaced residents from the upstairs apartments have been safely accounted for and are receiving assistance from the Red Cross.

Firefighters were able to save a kitten from an apartment. Paramedics gave it oxygen before it was reunited with its owner.

Pittsburgh Police secured the scene between S. 10th and S.14th on E. Carson.

The exact cause of the fire remains under investigation.
