Based on the statement, Tyumen region governor Aleksandr Moor said emergency crews were working at the site. He stated that the plant was not damaged and that workers were evacuated.
The Tyumen refinery processes about 151,000 barrels of crude oil per day and is an important supplier of fuel to Russia's domestic market.
