FREEPORT, Ill. (WTVO) — Two people were rescued by neighbors and flown to the hospital after a house exploded in Freeport on Tuesday.

Crews were called to a home in the 4000 block of US Business 20 near Harlem Center Road around 8 p.m. for reports of an entire house on fire. Debris from the explosion littered nearby roads as crews worked to block traffic on the busy highway.

The Freeport Rural Fire Department said the occupants of the home, a man and woman, had been helped out of the house by a neighbor and passerby by the time firefighters arrived.

Officials said the residents were taken to FHN Hospital and then airlifted to a Rockford hospital. Their injuries are unknown at this time.

Authorities said the names of the residents were being withheld pending family notifications.

The State Fire Marshall’s Office was called to investigate the cause of the explosion.
