A difficult fuel supply situation persists in several Russian regions, particularly in Siberia, where supply issues are being addressed on a case-by-case basis, Russian Deputy Prime Minister Alexander Novak told reporters, according to Izvestia. "The situation remains difficult in some regions, particularly in Siberia. At the federal headquarters level, together with the regions and companies, we are essentially resolving fuel supply issues on a case-by-case basis," Novak said. He added that the Russian government is discussing additional fuel supplies to stabilize the situation in Siberian regions. Earlier, Novak told TASS that Russia had accumulated sufficient fuel supplies to meet domestic demand, but panic buying had driven demand up by about 20%-30%.
