Excerpts from abc7chicago.com:

The Belleville Fire Department responded to reports of a fire coming from an apartment block on Freedom Drive shortly after 6 a.m. When firefighters, arrived they found a woman and two of her children had got out of the apartment safely, but a third child had to be rescued by firefighters. Helmet cam footage shared by the fire department shows firefighters searching the residence as the girl can be heard crying before they take her out of the apartment.

The four-year-old girl was transported to a nearby hospital for treatment.
