Excerpts from fox32chicago.com:

Two boys were injured, one critically, in an arson attempt Sunday night at a residence in the Englewood neighborhood after an object was ignited and thrown near the rear of a home around 11:36 p.m. in the 6100 block of South Carpenter Street.

A man and four children were able to exit the burning residence unharmed but told firefighters that a child was still inside the home. Firefighters recovered a 4-year-old boy from the residence. He was transported to Comer Children’s Hospital to be treated for smoke inhalation where he was listed in critical condition.

A 9-year-old boy suffering from smoke inhalation was also taken to Comer where he was listed in good condition.

The Chicago Fire Department is investigating.
