Vladimir Potanin, the co-owner of Russian mining company Norilsk Nickel, said in an interview with state television aired on Saturday that thawing permafrost was one reason behind a major fuel spill in the Arctic earlier this year.
The spill occurred on May 29 after a fuel tank lost pressure and released 21,000 tonnes of diesel into rivers and subsoil near the city of Norilsk in Siberia.
