Six people are missing and at least 42 injured after an explosion ripped through a sugar refinery in the southeastern U.S. city of Savannah, in the state of Georgia.
The blast caused a massive fire that firefighters were still trying to bring under control more than 12 hours after the explosion.
The refinery is owned by Imperial Sugar Company.
A company spokesman says the blast tore through a silo where refined sugar is kept. He suspects sugar dust, which can be volatile, may have caused the explosion.
About 100 workers were inside the refinery at the time of the blast.
