MOSCOW, Sept. 29 (Xinhua) -- A fire in an oil processing plant in Russia's Khanty-Mansi Autonomous Area in western Siberia has killed at least eight people, the Emergency Situations Ministry said Saturday.
Eight other people injured in the accident have been hospitalized, the ministry's regional branch said.
Alarm about the fire was received at around 09:00 Moscow time (0500 GMT). Earlier reports said only one people was killed in the fire, but later the ministry said eight bodies were found in the debris as of Saturday afternoon.
Preliminary information showed that an explosion triggered the fire in the processing plant, but the cause of the explosion remained unknown.
The fire, engulfing some 4,000 square meters, has already been put out. A probe into the fire has been launched.
Khanty-Mansi Autonomous Area abounds in oil and natural gas. More than 50 percent of the oil produced in Russia comes from this area.
