Careless smoking spreads to Bandar Abbas
At least 500 injured in huge explosion at Iran port
Witnesses say the explosion occurred after a small fire on the wharf spread to open containers storing "flammable materials" and most likely, chemicals.
"The fire spread quickly and caused an explosion," one witness told local media.
"The source of this incident was the explosion of several containers stored in the Shahid Rajaee Port wharf area," a crisis management official said, according to BBC Persian.
