A large fire has been reported at an oil depot in the northern Iranian city of Qazvin, some 130 kilometers west of Tehran.
Reports said firefighters had trouble controlling the fire, which was raging for hours without being contained.
There were conflicting reports about casualties with state television showing Governor Saeed Mibaha as saying there were no casualties while the semi-official Fars news agency reported some 50 people had been injured and many were in serious condition.
The Qazvin emergency department said one rescuer was suffering from smoke inhalation.
Officials have said they would provide more information after the fire is extinguished.
