Excerpts from abc7chicago.com:

An extra-alarm fire broke out around 3:38 a.m. on Tuesday in a two-story residence in the 2200-block of East 100th Street in Chicago. All residents were accounted for, but four firefighters were injured when the second floor collapsed.

Two firefighters were caught by the collapse. One was able to self-evacuate while the other was trapped. Both made it out safely, but four were transported to local hospitals with minor injuries.

As the Red Cross tries to lend a hand and as fire investigators sift through the rubble, neighbors who once called this home are now left without one.

The cause of the fire is still under investigation this morning.
