Officials say the death toll from a warehouse fire in Icheon, South Korea, has risen to 40.

Firefighters found more bodies Monday while extinguishing most of the last flames. Most bodies were burned beyond recognition.

Ten people were hospitalized for injuries, mostly burns and smoke inhalation.

Witnesses report hearing explosions as the fire ravaged the refrigerated warehouse earlier today. The cause of the blaze is still not known but officials say flammable refrigerant chemicals were stored in the basement of the building.

The warehouse was under construction and was scheduled to open at the end of the week. The victims were construction workers.
