Russia’s Federal Anti-Monopoly Service (FAS) has ordered two gas station chains in Moscow to explain recent price hikes, coming as intensifying Ukrainian drone attacks fuel rationing measures in an increasing number of regions. Neftmagistral, which operates more than 100 gas stations across the capital and the wider Moscow region, and EuroTrans, which owns 57 Trassa gas stations, both have until next Friday, June 26, to submit pricing data for gasoline and diesel sales.
