Investigators suspect a chemical reaction involving hydrogen caused the blast at metal and chemical company Mitsubishi Materials Corp’s Yokkaichi plant, about 220 miles west of Tokyo.

Police said five workers died. Fire department officials said that 17 people were taken to hospitals.

The dead and injured were all believed to be workers at the factory.
