ST. LOUIS - Three people are hospitalized in critical condition after an explosion at a manufacturing plant in southwestern Illinois.
Authorities say 10 people were taken to hospitals after the explosion Thursday at the American Steel Foundries plant in Granite City, just northeast of St. Louis.
Gateway Regional Medical Center spokeswoman Kate Allaria says seven workers were treated for smoke inhalation and have been released. She says the other three workers are in critical condition and were flown to nearby Missouri hospitals.
A spokeswoman at one of those hospitals says the two victims it received were in critical condition. The whereabouts of the other worker wasn't immediately clear.
Investigators were trying to determine what sparked the blast at the plant, which makes railroad freight car undercarriage components and related parts.
